    Universal Heliar 30CM Flange specifications

    Hi!
    I will have the opportunity to test a Universal Heliar 30cm in a camera shop to see if I want to buy it
    I will be using a Sinar P and I need to make a flange to mount the barrel lens to the lens board, but I can't take it out of the camera shop to make the measurements
    Does anyone know the diameter and thread specifications of this lens? I can't find it anywhere. I searched a lot of the forum post here about the lense but no luck
    Thanks!

    It may depend on the date of production.
    My early 30cm Universal flange is definitely a 90 mm, but is not the common 1mm variant (like the Compound shutter V flange).It is more like a 1.5mm thread spacing.

    From the table in https://www.antiquecameras.net/heliarlenses.html it looks like it is from 1935
    Do you think it can be the same model as yours?
    Thanks

    It is the same optical design - other Heliars became Dynars.
    Mine is from the first batch, that didn’t yet have the “Universal” engraving. Serial number 251345.
