Sounds like a 3/8-24 fine thread, 60 degrees. Nothing special, unless you're not used to non-metric threads. Check Machinery's Handbook or google it.

Looks to me like a British Standard pipe thread.

It may be a 28 pitch Whitworth insert to cut it.
Whitworth, aka BSPP (British Standard Parallel Pipe), aka ISO 228, has a 55° thread flank, not 60°.

Looks like a straight 3/8-24 to me.

24tpi would not be BSW, BSF or BSPP. 3/8-24 UNF is the only common one that meets the measured dimensions.
