Thank you for that, Max. The 77/97 spring was certainly among my list of possibles. It'd be nice if it fitted onto the TbT guides nicely. Or, I wonder if Nick might have some of his "old-type" more basic kits still knocking around?

I think Nick's 77/97 springs will be the same as the 35/80 ones, just different lengths?

I'll see who has genuine standard ones......
