I have a CZ Tessar 16.5cm with serial #273046, in compound. I've been trying to date it using the lens serial but it seems to fall into a gap. I estimate it to have been made in 1914. I had another thought of finding dates for Compound shutters and going by that. THe date on my lens's shutter is 259xxx. I buy a "new" lens of one sort or another almost every month, and it's fun to try to piece together their history.
Today I bought a very tiny Petzval, about 2 inches long and an inch in diameter. I'm hoping to have SK Grimes put it into an F-mount! I'll post photos when I get it, and disassemble to see if there's any info lurking within.
