I've extracted some decent lenses in Compound and Compur shutters from Folding Pocket Kodak Specials. The cameras were offered with gazillions of different lenses from different makers. IMO the best relatively common lenses fitted to them are f/6.3 Tessars, which were engraved Zeiss Kodak Anastigmat, Tessar, B&L Tessar IIb. f/6.3 Tessars from #3 and larger FPK Specials will cover 4x5. The 170/6.3 Kodak Anastigmat in Ilex shutter fitted to larger FKP Specials is the same design as the 203/7.7 Ektar, should do very well as a slightly long normal lens on 4x5.

Plan/budget for shutter overhaul.
