4 cav handle manufacture?

[randyrat]

I have some Lyman handles? that came on a 4 cav mold. I don't see these anymore, at least i don't. They open from the front. Are these older or are they a different manufacture?
The hinge is in front of the mold like a nut cracker. I don't like using them myself. they are on a 358 60

They are the older Ideal handles.

never have seen any difference between the old and new style.
