Initial AF Cosina Zoom Lens

Threatening Typhoon #9 is coming up to Kyushu to our land soon and not a few damage would be done without modest at all, flood damage will exceed others judging from the recent history. Anyway, any favorable weather condition would not be desired because of natural phenomena, I'll stay at home for the time being with organizing my own surroundings. As for a very outstanding Zoom lens obtained from Yahoo Auction at 300 yen that was produced while the dawn period of time in Auto Focusing system, now under servicing. All the AF mechanism were removed thoroughly including Piezoelectric Buzzer for weight reduction and all the constructive lens surfaces were cleaned wiping out clogged mold. My way of use for this lens is fully manual actions, both focusing and zooming, so auto focusing system has nothing to do with myself. Desperate effort of Cosina's engineers are observed everywhere newly invented mechanism especially focusing sensor position adjustment construction as shown in pics. Because I lost the constructive information, it will be reconstructed by referring the construction of auto iris controlling arm actions.
