ROKKOR QF 200/3,5 disassembled

Old Tele Photo lens produced in 1960, Minolta MC tele ROKKOR QF 200/3,5 was disassembled a part in order to examine the region to move 2 mm backward for establishing infinity focusing position when mounted on Canon EOS Digital body, 1,5 mm thickness of additional metallic flange and fundamental flange-back discrepant value 0,5 mm. The mechanical construction of barrel inside is so rigid as to surprise my eyes being familiar with recent plastic and delicate ones. Though some heavy and dull movement are observed because of lack of lubrication, no critical wear on important portions, probably this one was not used much to make backlash, in stead it looks like new one. No problem like mold nor scratches on the lens element make me swing pass to reconstruct this lens adopting on Digital image format, and further efforts would be required to complete the work.
