As said in another topic, I recently bought a macroFedlens. Till now, I have found three different series of this lens: - First one, with two pins and technical engravings on the barrel (examples, the # 107 of DVD collection or my #3). - The same without engravings, like the one Luiz put in the wiki. It would be interesting to know its serial #, Luiz? - Without pins, without engravings. The most common of the three ones.
It seems the lenses were numbered amongst the other accessories in the same range (1 to 15xxx, as observed): a bit surprising. The other special lenses had specific ranges.
Of course, I don't count the rigid unnumbered ordinary ones (said by two sellers to have been made after WW2 ??), nor the protos (Bill's one, for ex.)
Your comments? Thanks. Amitiés. Jacques. (BTW, the last picture for this lens in the wiki probably belongs to a 6,3/100mm (range of distance and serial number).
