Jimmy and I have been working with Sunset/3rd rail on a model of the M 4-8-0 and this is where the question about the top check valve originated. I have looked through the 1906 Locomotive Dictionary and a 1925 Loco Cyc. and have not found a drawing of a top check valve with rear pipe entry. If anyone on the list has other Cyc editions, I'd appreciate it if you could look for such a valve.
Here is a drawing (courtesy of Jimmy's son) of what we think it looks like: http://www.oscalemag.com/!models/TopMount.jpg
