Trying to find what thread this is, closest to it I can find is pipe thread but it's not quite right. This is universal model not sure what it came off , it's not the best pic Thanks for the help
No, it is not a pipe thread. Since it is U.S. made, I very much doubt that it is metric or Whitworth. So, without knowing what I am talking about (familiar to those who know me), I suggest getting a few fine thread (it looks like it) nuts of various sizes and try threading them on finger tight. Of course, you could always use a thread gauge to determine thread pitch. That would give you a headstart. Whatever you do, do not force anything. Last, but important, gently use a hand wire brush the threads to clean them up before trial fitting nuts. Standy by, someone will tell you exactly what the thread is. Some oldtimer, I'm a few years short...in my opinion.
Do a google search for boyce motometer parts.....there should be everything needed to restore them. I don't know what thread, may be metric or there were strange thread counts vs. diameters back then. That is universal for all cars. they came in several diameters, smallest will say "junior". They were available with different faces with car names or dealers names. here is a rare Ford dealer one from 1928 showing the ford trimotor. I sold it as i don't have an A
That was made before the standardized thread system was universally accepted. I used one on my T, just made a ring with 2 setscrews.
