I got myself a new old lens on e-bay. It arrived yesterday. The engravings on the brass read Standard Optical Co., Standard Symmetrical f6.8, Newark NJ, 8x10, Equi. 12 1/2. As suggested the lens seems to be of RR type and has maximum f6.8 aperture. It came mounted in the most barbarian way I have ever seen in the non-original Baush and Lomb brass shutter. I removed the lens form this non functioning shutter, cleaned the glass and tried it on Ilex #4 shutter. I initially wanted to have this lens mounted in this shutter. To my surprise the lens threads fitted the shutter, moreover, the aperture scale on the shutter begins with f 6.8. On the other hand it seems not possible that by chance this lens was indeed originally mounted in Ilex #4 as it is most likely much earlier then the shutter.
What do you think of that? Anyone has some information on this mysterious Standard Optical Co. of Newark NJ?
best wishes,
Jan
