Is there an archive of WABCO and American Brake Company drawings for steam locomotives?

We have had considerable luck obtaining most drawings for USATC Consolidation Alaska Railroad #557. However, the foundation brakes were apparently obtained as a kit of parts from the outside supplier and the foundation brakes were only referred to by the brake manufacture's assembly drawing number. For the USATC Consolidations, there was no further breakdown of the brake parts. From the few drawings I have seen, there were two types. One was an assembly drawing for the particular design number with the drawing numbers for the individual parts listed. Other drawings were for individual parts which showed the part and listed by number all of the assembly drawings that the part was used on.

The specific drawings were a searching for are WABCO Dwg 2132-B and American Brake Co Dwg. #2132-B

You might try Backshop Enterprises (303) 424-6882 So far as I know they got all the WABCO drawings, inventory, go/no go gauges, jigs, and patents, which they use to manufacture or rehab steam locomotive air brake systems.

Bernie got what Bert Williams had along with the compressor hardware business. I don't recall seeing any brake rigging drawings when I worked for him, but then never had occasion to seek them out. The Cyclopedias have some decent generic drawings in them for brake rigging that could help.

Sorry, Dave, check your PMs...

Thanks for the responses.
