MAINSPRING WINDER

From an old clockmakers workshop clearance...

This is a boxed set of mainspring winder/insertion tools

Alloy handle with knurled grip to hold the various bayonet fit spring winders into.

I had one of these before and it was branded Boley - but I can't find a name on this one.

I've measured the diameters of the spring holders as best I can see below...

All mainspring hooks seem good (except top left one which may need remaking)

One handle also has a hard soldered repair (still works)

As pictured...

ANY QUESTIONS?

SIZES APPX.
