Thanks for the list
its a bunch of mixed threads ;D
Meteric
BSP
BA (had to google these, must be the most British Thread ever. biggest is 0BA smallest is 25BA with a diameter of 0,25mm must be for watch makers )
UNF
;D
The Rapid 7 block was all BSP, BA and the single 1/4 UNF, because the 2BA tooling became harder to find Theoben just changed to M3.
BA threads were very much still in use... 35 years ago,
If you fish? Most indicator bobbins are 2BA along with a standard 3/8 BSF for bank sticks.
And of course dart body threads.
The Theoben Rapid is the Leftovers from Christmas Dinner!!
With the mix of British, Metric and even Imperial thrown in!!
Why????
But to make matters worst..
Chip Smith did the Same with the Titanium Rapids..All 9 of them!!!
He had to order special tooling for the British stuff!!!!
He wanted all the parts to interchange?!?!?
Just no Logic....
;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D

and on most theoben blocks,..nothing square,...some of the QC was shocking even in the last ones.
Pretty sure 2BA is also the thread on mains electric socket covers.
