Eric, OK - I can't take a picture right now but here's a description of the dropouts and the adjuster screws. Perhaps I should start with the following qualification: although these are genuine Simplex items (circa 1984) the right side rear dropout is threaded to accept a Campagnolo derailleur - or a Shimano, etc. I've seen them on a number of Peugeot models from that era, each using different tubesets. As for the adjuster screws... they are the same threading as Campagnolo (3mm x .5). They are different, though. The Campy screws are more like a threaded rod with slotted ends. Then you place a cap on the end that's outside the dropout. The Simplex adjusters are actual screws, and the screw's head remains outside the dropout. A hex shaped cap nut is then mounted on the end that's inside teh dropout. One other difference: these Simplex adjusters don't use springs. Instead, they pass through a plastic insert that's pressed into the dropout, sort of like the adjuster screws for a modern Shimano derailleur. Best regards, Fred Rednor - Arlington, Virginia
