Serials of pre-war FED lenses and accessories

Ah, I didn't know diferent versions of the meter existed.
Do you know examples for ones made of brass or aluminium?
Would be interesting to see if certain serial ranges are made from a particular material just like the shutter cages.

My light meter No.11153 appears to be made of aluminium and weighs about 225g. But my scale isn't very precise, I'll weight it at university tomorrow for better results.

By the way - I have the clam shell leather case for it too.

Jacques, I noticed you found a FED 100mm f/6.3 lens with a strange serial on ebay: 355469

What could have happened here?
My first guess would be that the "5" was accidentally stamped twice. Does the lens, apart from the serial, look different in any way?


Here's a rare example of a singly-sold FED 50mm f/2 lens:

Yes, Christian. Certainly a faulty double stamp.
I try to find it out, if it is always for sale.

Amitiйs. Jacques.

Here it is:

Faulty double 5 evident... Same pressure and defect for the stamps.
And this lens belongs to the 1st series, with two pins.

Jacques.
