Info on Todays antique shop finds

Found these three today while hunting around some antique shops. If anyone has any info and value, especially for square pan jump, I'd appreciate it.

OC no. 2 double jump w/square pan




Triumph Easy set...in rougher shape but I've never seen one and it had drag so had to pick,it up



OC Victor no 4 w/ warranted pan

IMO the number four on the bottom is most valuable but I think it has wrong chain

I thought that myself, but wasn't too sure on what the chain should be on it. Can't really seem to find any info on the two OCs to verify
