I wanted to include this as well but it had a question attached so I’ll just make it a post here:
1.) Are these Marx Mercury Wind-ups
or
2.) Are these Joy Line (something) Windups
Considering they have the swinging peg- I assume they’re Joy Line? Or some kind of modification. Also- the loco with the green platform is has a different, I believe a bit earlier, mechanism or design than the other. It won’t wind up with the Marx Key , and, if I recall correctly a nail is supposed to be used to wind it up?
Feedback or conjectures are greatly appreciated! Got both of these from my pop, have a feeling he tried to fix the one with the green platform because that was my pop, there were few problems glue couldn’t handle- luckily certain parts of trains fell into that exclusive category.
