Weird Question About Old HO Switcher Models

[Doughless]

I think AHM made an Alco S2.  Seemed a bit oversized, and was not a good runner, but pretty sure it had truck mounted couplers.

Actually, found one. And, yes it does.  It was also sold under the name ALCO 1000.

I need an HO scale switcher locomotive, suitable for 1954, with TRUCK MOUNTED couplers.

.

I have searched around eBay, found some old trainset road switchers and F units with talgo couplers, but not a small switcher.

.

Any ideas for what I should be looking for?
