What is this old S&G?
Unfortunately, the wheel pack only has two wheels in it. Someone threw some other lock parts under the wheels as spacers- a movable fly, and a hole change fly with a broken tab. I suspect the broken hole change fly (numbered "8", for which I will make another thread) was originally from this lock, and its breakage is why one wheel was removed. I don't suppose anyone knows where I can find a wheel and isolation washer (.5" ID) to make this lock complete?
