The 2342 is a nice little motor. I use them in small steam. I think the last one was in a Kemtron Wabash Mogul. Very powerful and quiet. Nope, no gear head. Really short 3mm output shaft on the backside. If you add a flywheel it needs to be pressed on carefully. The longer shaft is closer to 2mm and will need a bushing for most anything we do in 1/48.
Originally I bought a box of 50 and ruined about half when trying to remove the gear. The ball bearings didn't like the abuse. Rod Miller provided and one of those teaching moments for me and taught me how to press the off without damaging anything but the gear.
First one went in a Westside SP 4-8-0 and the corresponding motor mount worked so well I had a master made and now have them cast up in brass. Two to four screws hold the mount to the frame and a single set screw holds the motor in the tubular mount.
The price is about middle of the road. I think I bought the last batch of three for a little over $100 on ebay.
All in all, a far superior motor to anything else in it's size range.
If you buy one and want to try it out feel free to ask me any questions you may have.
I tried to add some photos but was allowed to. I'll go do the photobucket thingy and do it that way.
SP TW-8 with the 2342 Faulhaber, NWSL gearbox and all new drivers. Done years ago. Shown mostly so you can see the motor mount.
