Just came this morning, One of the models i've been seeking out for years. I don't know too much about the model, All I know is that it's made by Shinsei in 1:48 scale, But from the lack of pictures and information i'm going to assume is pretty rare. There were only 5 models made that I know of.
10-H4W 1:40 scale by Diapet
12-HT 1:48 scale by Shinsei
15-HT Unknown scale by Tomica (Pocket Cars)
20-HT 1:43 scale by Tomica
PC1000SE 1:50 scale by Craig (aka) caucasianaasian

Shinsei #4602 Komatsu-Bucyrus 12-HT-1 was one of the initial Shinsei Mini Power "Wide Series" of models and was produced in Jurong, Singapore.

The undercarriage, boom, stick and bucket castings have been used on all the subsequent Komatsu PC100s. Only the cab and superstructure of those models were different.

As far as rarity is concerned, it would rank second in the series. The Komatsu PC100-1 is certainly the rarest variant.

Hi WCollins
I have three of your list, the Komatsu 15-HT is a scale of 1/103, note the cab is on the right as was the real machines. This led to a few cabs been knocked off when being transported on low loaders through round tunnels in Japan. Hang330c you have the model i have allways wanted any chance of a few more photos. This link shows a few Komatsu models and dates

Shinsei made every generation of the PC 100 up to the LC-6 generation. I think Tomica Dandy also made the PC200 up to the LC-3 or LC-5 Generation. These are all very cool models too, I always enjoy seeing older komatsu equipment.

Hi John

Thanks John for the pictures.

I was not sure if the model I own was a -1.....it's exactly the same as yours
with two differences: the tracks on mine had to be changed as they dried out and the exaust
is half broken due to the plastic quality.

Hey Mick,

Well; we certainly have the same box, if not the same model! Just kidding of course.

Although I'm not fluent in Japanese, I do know how to write and speak numerals. I wish I knew more and could translate for you, but I can't. I can tell you without doubt that that the characters after the "PC" under the old logo on the box do not represent any numbers that I am familiar with in either On or Kun.

In retrospect; I don't know why I called it a "-1" other than that is how other collectors refer to it, and is the same unfounded phenomenon which causes people call the orignal Caterpillar 988 an "A" when it's actually just a 988. Also; even though the box lid is bi-lingual there are no suffixes listed anywhere in the English box text. It's simply a PC100.

Yes; the early Japanese models had horrible self-destructing tracks. The rubber they were using at the time just had no "life", for lack of a better word. Even worse than the Shinsei tracks were those on the Diapet models. The absoute worst were the Grip models (95% of the people here won't even know what that means). Does anybody here remember them?

The best advice for most old Japanese models with rubber crawlers is to keep them out of any sunlight and at a cool temperature.

Just out of curiosity; can either of you speak to how rare these pieces are in the UK and Europe? My opinion was from my own experience. I would like to hear your opinions please?

I remember those, I had a Grip Zechin Cat D5 a few years back. The tracks almost turned into a pile of rubber chips. I didn't have any problems with the Diapet tracks, But the Shinsei tracks on the 12-HT were cracked all over so I put the tracks off a Shinsei bulldozer, There a hair smaller but they fit.

Hi guys,

Just saw this thread, I don't get online that much at the moment.

The characters after 'PC' spell 'series'. シ (Shi), リー (Ri - with a long sound), ズ (Zu). So the whole thing is Shirizu, which is you say fast sounds like the English word 'series'. Sorry, just a quick Japanese lesson for ya.

On another note, if anyone has any of the 20HT Tomica Dandy models (or other Tomica Dandy Komatsu models) for sale, any condition, don't hesitate in PM'ing me.

Cheers,
Craig

Good topic,
All i need to do now is to find a 20HT and the first Komatsu PC200 to go with the models in the photo.

WCollins,

It's good to know that I'm not the only person aware of Grip Zechin. There were some very nice pieces in the series, but textured rubber bands with no elasticity ruined the crawlers.

There was also the larger Grip Technica series that were very similar to Shinsei in execution but had features like opening doors. There were only four construction models that I'm aware of. Hitachi crawler excavators (one with backhoe bucket and the other with a clamshell) and two 4-axle truck cranes (one lattice and the other hydraulic telescopic).

Micko,

That's a nice collection of old school Komatsu models, but there are still a lot more from that era including some you may not even be aware of like these that were never listed in the catalogs;



Regarding that PC200 shown on Yidsu's site; it's a custom piece without doubt, but I have my doubts that it was one of caucasianaasian's altered Tomica Dandys considering the Joal tracks. It's certainly the Dandy undercarriage, superstructure base, boom, stick and bucket. The cab looks to have come from directly from the Shinsei PC100, and is disproportional to the rest of the model. The rest is either completely scratch-built or the PC100 castings have been cut and added to. It's a very nice job regardless, but let down by the out of scale cab.

Did your PC100-3 (Vanguard series in NA) come with yellow tracks? All that I've ever seen have had black tracks.

Have you got a list of Komatsu models from that era or better still some photos. W120 is this the same Wheel loader but one is fitted with a log grab on the front ?
I have two PC 100-3 one has the old decals on and the other the new both came with yellow tracks, one track broke on the oldest last year and it looks like the other track is about to go. Both models came from Komatsu UK when i worked there so tracks are original.

micko,

I guess I have a list in my head, but not put down on paper. Shoot me an e-mail shovelman@live.com and I'll send you some photos of other models.

Thanks for posting the photos! Not only yellow tracks, but distinctly different shades of yellow! The decal variation will find me digging out mine to see which one mine has.

The W120 wheel loaders are larger than both the J65 you referred to (which came both with a bucket and log forks) and the 510 which you have already. If I find the time to dig them out, I'll post a thread on them.

I'm enjoying these threads on old school models!

x2 I am enjoying these post as well. Since I entered this hobby only a few years I am really unaware of what was/is out there from the past. These post have been a good education in the history of our hobby.

very interesting, no not the damaged tracks but the model. It looks like the same casting was used to make the Komatsu PC 200-5 as was used for the -3. The door opens and the grills on the engine covers are the same. Komatsu have never made a -4 excavator so -5 followed -3. A PC 210-5 was made by Goods Wave but does not have an opening door the engine covers were different from the real machine but it does come with the self destructing tracks.
