I've been trying to clean house and have a couple of oddball lenses I'm having trouble figuring out. Any thoughts of the value/utility of these? There isn't too much online about either.
I posted a few snaps of them here:
75mm f14 SOM BERTHIOT PARIS PERIGRAPHE SIERIE VIa in pretty good condition, no shutter, and in some sort of "cup" that might fit into a shutter?
The 16 and 3/16" Bausch & Lomb Protar has the coating coming off and the shutter is non functional- but the weird thing is that the front and rear cells have the same focal length stamped on them. From what little I've seen of Protar lenses, I thought the front and rear was meant to be interchanged?
Any thoughts as to where to find more info? Are these of any value? Should I just put them back in the closet?
