Ross I would say the RH400 is from the master Peter Keim.

Wow, great to see new pictures of some Keim models! It would be great to see some comparison pics between his and the OHS model! Can't wait, thanks for sharing! Rowan.

Outstanding photos! Thanks for taking the time to share them. I realise that the NACG white version is a much newer machine and heavily evolved from ther earlier red model but it is noticeably higher, Does anybody know if the earlier red version actually lower in real life or is the OHS scale off? Perhaps OHS = 1:48? Rowan.

Hi Rowan
The original RH400 (11.35) was lower on the carbody to the top of the tracks. The later 11.37 machines had the carbody higher to give greater clearance to the top of the tracks because in the tar sands the material sticks to the tracks and was getting driven into the carbody and damaging the body.
Also the later machines were CAT engines which led to major changes to the rear body for air flow etc and as the success of the 797 took off the cab went up higher to improve visibility into the body.
The OHS models are pretty accurate, with the 11.37 example being the most accurate of the 2 versions.
I am sure Brian (Greasemonkey) will add anything I have missed.

Rowan & Richard,
The first 2 units {11-35/36} had single level upperstructures as they were both essentially prototypes.With the following 3 units {11-37/38 and electric} the cab was attached onto a component which elevated it by approx 850mm.The counterweight was also increased and when fitted, was also 850mm higher than the level of the engine module.Other upgrades were also made to these shovels- on the attachment and undercarriage.
The 6th unit{NACG} and subsequent RH 400 shovels all had higher/taller side engine module covers added which increased the height of the module to allow for a single level upperstructure again,which certainly looked much higher and 'beefier' when compared to the first 2 machines built.Only the oil cooler module has not been heightened and is noticeably lower than the rest of the deck on all the most recent shovels.
Perhaps Greasemonkey has more info to add to mine too.
Regards
Brian C

You guys pretty much covered it, the only thing I would like to add is that Peter has the undercarriage a bit too high compared to the real thing, this really adds to the height of the model in comparison to the OHS version. I'm not trying to fault Mr Keim in any way, but typically, he builds his undercarriage a bit too tall on most, if not all of his O&K models.
It's still a work of art though.

PS. Sorry to divert off topic however, I suppose you would need to talk to the man directly, however if you wanted a highly expensive, highly detailed model of a certain model that isn't in his current repertoire, will he build one? Rowan.

Brian,
I agree with you on the height of the track frames/top rollers.The shovel lip has an additional tooth {7 instead of 6} That said,I would love to have one of these in 'Canadian Natural','Citic Pacific Mining' livery or even Anglo Platinum's electric in my collection!!!
Time will tell if that ever becomes a reality

I know there will be a few more of the RH400s made from the OHS masters. The question at this point is how many, and when.

Didn't 11-37 and 11-38 (real machines) have a slightly longer boom as well?
Please use this before clicking "post"??? You may be surprised with what you see!

Brian C wrote:The shovel lip has an additional tooth {7 instead of 6} It's interesting that the model was built with a 7 tooth bucket, since the only machines to actually come with a 7 tooth bucket were 11-35, 11-36 and the number 5 machine which was electric driven. The 7 tooth buckets were removed from 11-35 and 11-36 and they were subsequently run with the 6 tooth version. Shovelman wrote:Didn't 11-37 and 11-38 (real machines) have a slightly longer boom as well? Yes, 11-37 and 11-38 have a longer boom than 11-35 and 11-36. In fact, the first two machines were the only ones built with a shorter boom, and it has proved to be a bit too short for the machine, therefore, all machines built since the first two (11-35 and 11-36) have had the longer boom.
