Thanks Lynn, I’d appreciate that.

Yes, this is an earlier model with no provision for a circlip. The main spring tail secures the other link and I suppose the original designer felt this was enough to hold both links on. I’ve gotten well more than my due use out of this one but I like to give parts another chance.

The closed end sleeve that the lever arm slides over actually spins on an inner pin. Without breaking I couldn’t see if it was possible to secure with a screw. Looks like it can!
