I think I see the first poster's point.
SR&RL Baldwins 10 (and maybe 9?) did have outside Walschaerts valve gear:

...but as many have pointed out, the models do have inside Stephenson valve gear:

But, the (Bachmann) locos are also "supposedly" Baldwin catalogue locos, and probably was what was on those offerings.
Maybe why Bachmann chose non extant for SR&RL #s 11 and 12 for their offerenings?
Food for thought......
