Found 5/16-12 die for $35 to $100.Major thread dia. Is slightly more than 0.30....5/16 is .310
Measured 3 threads per 1/4 in., 6 threads per 1/2 in.
Thus I would say the thread size is 5/16 -12. Doubt it is metric as it was wanufactured in Canada by Pioneer I believe.
I will check with a friend to see if they have this die at his machine shop. Would like comfirmation before spending that money.
Thanks!
