C W Burfle posted:The 1964-66 version had the plastic tender. The 773W, 2046W amd 2671W all use the same basic shell, but there are variations in the castings and there are fairly good reproductions out there.
For example, the correct 773-117 tender shell should have an oval shaped blank number board on it's side. Not certain about the other details, such as the area around the ladder on the rear, and which shells have open versus closed backup lights. I'd have to get out a reference book for other casting changes.
I'd be interested in the information or sources for information. I hope it includes information around RMT and other reproductions, the 2671W-6 stamp, and other things I probably don't even know:
