I just thought of something,...
- I have a friend, I met on e-bay.
(We Actually 'met' for real, when I made a roadtrip, last year, up through his area)
Anyway,....been friends for Years,....the recent meeting, was just an afterthought,....
Anyway,....he's a black-powder 'Sutter'
He has a cool shop PACKED with antique tools, and knows even more than I do,....
I'll send him the pix, and find out what it is.
(and it'll save me digging in my books/shop)
Will let ya'll know, what I find out.
