Awesome thanks guys! I might update the photos and take new ones minus the identified parts to make it easier to see the rest.

That #10 Chain and collar- looks like it might belong to vintage Joe Croc Master..

Thanks again! There seems to be a lot of loose GI Joe parts here!

Here's a good site for IDing GI Joe parts...

Thanks, I've already used that for a few parts. Some of the parts I have though don't seem to be on that identification site and I was able to confirm that they were GI Joe related elsewhere eg. the crock master collar, which isn't on there as far a I can tell.
