Help to ID mold

[dbldblu]

This mold is unmarked except for C-257-938. I am leaning towards it being an early H&G mold but other opinions are sought.

It's a Modern Bond mould.

It's a Modern Bond mould.

That would be my guess, too. IIRC Modern Bond molds were marked with caliber and length of the boolit. As such, your's should cast a .25 caliber about .938" long.

What they did for different boolit designs of the same length, I do not know.

Thank you both, I agree it is a modern bond. It was a stock design apparently intended for the 25 Roberts (according to castpics).
