Does anyone know a good source for side dump hopper bottom ore cars that would have been manufactured by the Pressed Steel Car Company in the early 1900's?  I am modeling the Verde Tunnel and Smelter RR in my home town of Clarkdale AZ, which has several PSCC side dump hopper bottom ore cars ranging from 50, 60 and 70 ton capacity cars. 

Does anyone know whan knuckle couplers started to show up in HO scale, and how long the transition era was from horn hook to knuckle couplers?  My model railroading ended ~1980, when i bought what was cheap, and resumed 6-7 years ago, when horn hooks were occasionally seen in an older box that had clearly been on th hobby store shelf for a long time.

A friend of mine is working on a brass D&RGW L-105. He looked for rear views of the locomotive but found just L-131 tender photos showing a back-up light.

Now the question is, does the L-105 have the same light? It seems to be the same type of tender. I have a Mainline Modeler drawing that shows just class lights on the back of the tender.

Thank you for you assistance

I'm rebuilding a Proto 2000 SD45 to Northern Pacific standards.  As the NP had 4 side windows on its SD45 cabs it required an entirely different handrail arrangement where they attached to the cab.

Does any company make an accurate set of stanchions for use on an SD45. I did this to an old Rail Products shell years ago but can't remember what stanchions I used. They were accurate and made from brass or copper berylium.
