info on 8x10 Bausch & Lomb Tessar Series Ic f4.5 Large Format Lens
hi
i just bought this lens on ebay and wanted to find out some info on it.
the seller knew nothing about it.
does anyone know if the flange fitting it would be metric or imperial threading?
or the size of the back of the lens?

"does anyone know if the flange fitting it would be metric or imperial threading?"
neither, they would be US sizes and TPI, you need a B&L flange.
B&L used their own US sizes and TPI that sometimes interchanges with Kodak
Kodak used their own US sizes and TPI that sometimes interchanges with B&L
Ilex used their own US sizes and TPI
Wollensak used their own US sizes and TPI
these also almost never interchange between brands.
"metric if in say a Compund shutter"
no, B&L licensed and produced the Compound shutter in Rochester with US sizes and TPI.
