Looks like your 0-8-0
This looks like it could be the SP 0-6-0 O Scale Brass Model Train - GPM Glacier Park Models SP Southern Pacific 0-6-0 #1269 - Black Boiler | BRASSTRAIN.com like your
Hi there. You might have better luck on a O gauge 2 rail forum - most folks here model HO or N scale. I can only guess: the 2-10-2 might be a modified Rivarossi engine. The other 0-6-0 could be Varney or All Nation. Only real full-time O gaugers would know!

I found these brass locomotives at a car swap meet this weekend, and I've been trying to find out what they are, and what years they were made. Going from back to front:
-The 0-6-0 is an Southern Pacific switcher, but I have no idea who made the kit. What is odd is that the hump for the gear underneath is the same depth as the treads, which would short out going over a switch, or on the center rail when I convert it to 3 rail ;). No markings on it other than the paintwork, which will unfortunely need to be redone as primer wasn't used leading to the paint chipping off.
-The 10 wheel chassis may be a 2-10-2, but it's made of plastic. That lead me to think it may be a stationary model kit, but it has a gear on the center axle, so was it made to run? The rear truck is a really nice piece, even has opening journal boxes. Also no markings, so no idea of a maker.
-This 0-8-0 did have markings, and it's a KTM USRA switcher chassis. There's not much info on these online, so I don't know the year.
My plans for these are to put motors in them so I can at least watch them run on rollers, but that will take place after I'm done my Engineering Technology schooling in the spring. At some point after that I will try to convert the 0-6-0 and maybe the 0-8-0 to 3 rail. The 10 wheeler is missing too many parts unless I find a donor, plus it's plastic which impacts pulling power. Thanks for any help!
