Details:

I got this as part of a collection and have no idea if it works, but see reason why should not. The brushes are missing and the screws that hold it together, but otherwise looks fine, please see photos. I am unsure if this would be the same motor for 21115 Pacific, but it might. I say most of the time, because will, on some occasions, ship in previously used cartons and may reuse other types packing materials, which best suit item being shipped.

BUYER PAYS $8.00 FOR EXPERT PACKING AND FLAT RATE SHIPPING IN THE LOWER 48 USA !, IMPORTANT. I have a 21129 Hudson and both the 21139 21140 Northern this motor reverse unit look like they are exact match for parts in those locos. This motor is definitely larger than the one used in 21145 Switcher. What you see is what get.

I am selling this AF Motor Reverse Unit as-is, as-found. I've been around for a while a LONG while and I have dived into my last dumpster looking shipping cartons. I sometimes use USPS Priority Mail shipping cartons as well. I am selling this as untested and absolutely AS-IS.
