Attention disc box buffs -- I have a quantity of mainsprings for disc
boxes. They were produced in the UK circa 1980 before legislation
kicked in that governed the Rockwell Factor. In a nutshell, they are
up to the job.
I've only had to replace two springs in 30 years, so if any one needs
one for a Mikado or model 103/104/105 / 15-1/2-inch table top, I would
like to move them along. There are a couple for 21-1/4-inch Symphonion,
which, if I remember correctly, also suffice for 22-inch Polyphon.
