Photos or drawings of Big Boy Tenders

[RME]

UP has the drawings, and might provide them for reference or even scan them for you if you ask them politely.

If that takes too long, you can buy copies of the relevant drawings at reasonable scale here.

The catch is that what you actually want is pictures of the centipede tenders being fabricated.  I dimly remember something about centipede tender construction being outsourced, so your diorama might not involve actual tender framing from the pedestal water-bottom bed up... someone who is a UP fan or has the necessary Kratville discussion, please let him know.  It may be a problem that the 4000s were built during wartime when there was more of a 'ban' on photography even within production facilities, so there may be more work involved in finding sequential photographs of tender construction. 

It's possible that some in the picture-trading or slide-trading community have 'unpublished' photos of this.  They'd probably have no objection to your duplicating the subject matter of their photos in another medium.  Since I never actually got into that world I don't have any contacts to suggest, but people on this forum will surely know some of the 'right' folks.

I am building a proto typical erection building in HO scale of ALCO's final assembly plant.  I will show four 4-8-8-4 Big Boy locomotives and tenders under various stages of construction.  What I need is photographs or drawings of the inside of the tenders so they can be shown under different stages of construction.

Thanks, Jerry Blair
