Mainspring Tool Identification

Hi,

Does anyone recognise this? Like a normal Swiss winder except the arbors are completely different and the hooking point is much wider....

Could these maybe be for winding in mainspring slipping bridles?

It might help if we could see all the writing and a photo of the whole item.

looks interesting,  try it out,  at the  worst - it might just be home made.  cheers, vin

Here it is in another photo. It's of the same construction as my Bergeon winders. It's just the arbors which are different:

Well spotted! I guess it is an automatic bridle winder then. Should be pretty handy as I already have a set of normal mainspring winding arbors/handles, but this Eterna set has odd sizes included which my Bergeon set doesn't already have.

Thanks.
