Summaron 28mm f/5.6 LTM

[kkdanamatt]

I can't find any serial number on this lens.
Where is it?

It may be etched into the retaining ring under the front element. I had a 35 3.5 Summaron and that’s where it was.

Might also be on the ring around the rear element.

I just looked at my 50mm Hektor f/2.5....same thing...no serial #.

Serial number engraved at the rear, around the rear lens:

Thank you....there it is!

Now, can you help me find the 50mm f/2.5 Hektor's serial number?

 

[a.noctilux]

if not there at front, I can't help ...
or maybe it was mounted on a fixed lens Leica, so no serial n°

If the name ring of the Hektor says "F=50mm" it is an old one that was once fixed on a Leica I body that is converted now. The serial number is scratched inside, you can't see it if the lens is not disassembled.

If it says "f=5cm" it is a later interchangeble one.

On mine it’s on the black ring on the front, like a.noctilux’s. Not there on yours?
