I recently picked up a 412385 boolit mould... No vents, detachable blocks. The construction of the blocks screams Ideal / Lyman, but other than the boolit number, there are no marks on the blocks.
143880
Smooth block faces, ornate font. I didn't see this in the 1900 handbook, or in the specials in the 1929. Boolit has been cast with what appears like WW, poorly fluxed.
143881
Though marked 412, measurements show otherwise at this time. I had to measure with the boolit in the mould, as the sprue is in the hole. Most likely works fine with 20:1 or softer above black powder. The Lub grooves seem to suggest use with BP as well.
OAL of boolit is 1.218
Top band - .404 (right where nose meets groove diameter)
Second - .404
Third - .404
Fourth - .411
Fifth - .411
Sixth - .411 (base band
143882
Look at the trunctuated cone screw head.
143883
This shows the way the sprue plate is relieved for the stop pin.
