As I'm sorting through the boxes of parts, I come across some hardware, particularly quite a few nickel plated bolts, a variety of fork nuts, and some odds and ends. The first pic is a "3" stamped bb nut. I was curious as to what manufacturer used this. The bolts appear similar to seat post clamps bolts that schwinm had used in the early 60s and on, but again some are nickel plated and was not common in that period. Any information is greatly appreciated.

Do you have pics of a complete Thompson bb? I'm trying to make sense of these parts...or atleast put some of these components back together
Your missing a pressed in BB cup. The toothed washer goes on then the lock nut.The crank arms would then be cottered crank arms

There is not to much to a Thompson bottom bracket, in most cases they have a dumb side and a smart side with bolt and washer, you will find them on 3rd world bike and really not used on bikes in the USA. a little tinkering should unlock the key. Most of those bolts are stem clamp bolts and some truss bolts
