Thanks for the pic of the 5047, Nick - yes, I'd say that's what the builder was going for, and the "rubber ruler" modification to the length is nothing worse than LGB themselves have done in the past!
The frames on the motor blocks (and thus most likely the blocks themselves) are definitely 2095, with the cranks removed - wonder what he did with the cranks, they seem to be quite sought after these days (someone was wanting a pair on here just a short while ago?). My comment about not using the 2095 CHASSIS was exactly that - I suspect that rather than using the complete 2095 underframe, which of course has both power blocks recessed into it, he's simply mounted the power bogies under the original coach chassis which would account for the overall ride height - the coupler height would still be fine as they are mounted on the power bogie frames.
I'm sure that both ends are powered and have metal wheels - I think the shadows in one of the pictures make one set of wheels look darker (and hence like plastics), but if you look at the full side view pic you can see shiny tires on both.
Looking at your prototype pic, I'd actually say this isn't anywhere near as bad a job as some people first thought?
Jon.
