Can anyone name what mold this is? An old Ideal double cavity

What numbers are stamped on the side?

Looks like the cavities have brought cut line that’s not like ideals I have. Possibly a custom cut mold out of different blocks?

the dual direction of the machining lines, make me think it's modified.
Maybe a paper-patch design?

No idea, does look interesting, like upside down crimp grooves.

Doesn't look like anything catalogued in my oldest Lyman Cast Bullet Handbook. (#1, 2nd edition). Have never seen anything with a tapered lube groove so I also suspect that it's a rework of a different design.

It is labeled as a 358432

Definitely a rework. According to my old(est) Lyman Cast Bullet Handbook, the 358432 is a 148 gr. .358 wadcutter with two grease grooves and a crimp groove.

That is definitely a Bubba'd boolit mold. The 358432 is a button nose wadcutter and that aint it.

..............From its overall appearance, and especially the drive band treatment, it appears like it may have been modified for use in a BP firearm. My guess would be a revolver.

Definitely not the WC mentioned.

323062 is what it looks like more than that http://three-peaks.net/Lyman_and_Ideal_Bullet_Molds.pdf
