Thank you

60’s Stuff, the photo showing the blue return spring is very interesting. It appears different from the reproduction springs available. The reproduction has a group of coils near the center with a straight section ending in a hook on either side of the coils. The spring in your photo appears to have coils end to end with shorter straight sections that end in a hook. It even appears to be wound from larger diameter wire. It’s hard to tell though without seeing this blue spring in its relaxed state. Maybe it’s an optical illusion. Are these springs really different? Interested to learn anything additional you may know.

Thanks for the additional info and pics. I guess the blue spring is a little different, especially the offset hooks feature which appears to be included on the reproduction that our host sells. Would have never picked up on this if I hadn’t read Joe’s post and your reply. Filing this in my TriPower file for sure.
