I also buy up taps, dies, decent drill bits, files, that I find and like you,
have a collection of obsolete sizes, just not the right one.
Thanks for the info, much appreciated.

I occasionally run into 12-24, and some small sizes like 5-40 4-36 on dividers
and calipers, the choices are endless on old stuff.  I just buy every old tap
and die set I find.

I got my pair of 12-20  at $40, but now more availability
