Anyone out there know what size and pitch the three screws are to attach the two halves of the control head together on a 59 TR3A?
Nothing in my assortment seems to fit and I do NOT want to strip the brass inserts.

More then likely, they are British Association (BA) threads if they are smaller then 1/4". A lot of the screws smaller then 1/4" on the TR3 are BA threads. See the chart I linked to. The only sizes that I've run across so far are 2BA and 4BA. If the screw measures about 0.142" it's a 4BA, 0.185" = 2BA.
 
I had one measured at fastenal a couple of years ago and they gave me these numbers: M 2.5 x 60 x 6 Unfortunately, they only sold them in 100's. I made do with the old ones.
