I will obtain the correct 1/2"'Seeger' Circlips tomorrow, the ones that were installed were incorrect as was duly noted. Although they did their job many years, they should be correct. Just like the mis matched pistons m'lady had when I got her. It is my belief that she was recommissioned at a time that items were not easily available for our machines. 70''s or 80's perhaps?
My brake adjusters were not the wing nut style, but a machined piece as were the pins in the rear brake levers. I am thinking they were unavailable when the bike was worked on? It took me a while to figure out as I was totally uninitiated and when I tried removing the pins from the rear brake levers it was impossible because they were not slotted, they only had a hole for the shaft. It took me a short while to realize they were hand made...
There were other indications...
