I've got a pair of powerfolds with worn out gears. I was hoping to source some gears from somewhere but I have to face it, with my record, I'll never get round to it.
If you don't find anything else, will bring them to th next meet.
I don't like signatures, they take up too much screen space.
I think I may still have some non-powerfold mirrors in the garage - sans glass. They're not much value-wise so your welcome to them if you wish (and assuming I still have them! It's dark now but I can check tomorrow)?
