I recently bought this loco, and am waiting on it to arrive, but I cant seem to identify it from the photos. There is no number, and the seller did not say anything about it. The winding mechanism sticking out of the side is different than anything that I've ever seen before, which leads em to believe this could possibly be a prototype. Any info would be great.
I have found a few engines, but none have the pyramid cut out that surrounds the winding mechanism, most are just a semi circle.
