Piesker & Co. Berlin PICON 2.8/100mm

Thanks for opinion. As the founder of the company I already met the version about Paul Piesker.
However, there is an opinion that it not the producer, and the company which was engaged in import of photoequipment to the USA.
It is difficult to present that in the destroyed city through such short time without participation of military authorities restored production. And it is already absolutely improbable, this creation of the new.
I will be very grateful for any additional information.

There were at least two other Berlin-based optics companies after the war - Astro Berlin, TEWE... - which managed to resume the production, so it seems it was not that improbable, at least in the 3 West sectors.
As a small manufacturer, probably just a larger tooling workshop with a design bureau attached, they could be sourcing their glass lenses ans elements from larger manufacturers (even from Soviet occupied territory) and simply put them together in their own lens barrels. The Piesker designs weren't that complicated either - mainly triplets and later some 4-lens-designs.
