My father passed away last year, and my mother and I have begun to go through his things to decide what to keep and what to sell. He was a photographer for many years when I was younger and had a large collection of all sorts of cameras and accessories.
I have been trying to locate any information I can on these 2 pieces, because I need to know what they are valued at, and exactly what they are.
Any help would be greatly appreciated.

The picture below is of a lens that reads:
LOGETRONIC 5 3/4" (147MM) f/1.9 SUPER LOGETAR



The other below reads:
20 IN.E.F. BS2554 PAT.NO.1.971,434 and had notches for 10, 11, 16, 22, 32, 45, 64



I apologize for the terrible pictures. Please, if you know anything about these pieces or their value email me directly at pollydowner@hotmail.com. Any and all information would be greatly appreciated.
