Cooey bolt knob thread size

[Grizzly Adams]

So, I've decided to make a replacement bolt knob for my Cooey single shot, but I can't seem to find the thread size anywhere. Anyone know what it is ?

1/4 x 20 I think

I know they used 12-24 for the 39... knob was lost on one and I bought the tap for the knob I made and also the die to chase the handle threads clean.

I made it out of aluminum, the threads on the bolt looked a little stripped, but I drilled the hole just under size and it worked.
