Ideal/Lyman mold markings?

[Vulcan Bob]

Hi all, I was just wondering, after the purchase of Ideal by Lyman (1925?) when did the molds get stamped Lyman? I have a Lyman 358311 with a 1-57 stamp and just got an Ideal 357 446 with no date stamp but inscribed by an owner with 1-56 and his/her initials. I know not a pressing question but this aroused my curiosity.

I know they kept marking the molds Ideal for quite some time after Lyman bought Ideal. I'm not sure how long, but I belive there is a chapter on dating Ideal/ Lyman molds in "From Ingot to Target" which can be downloaded from the lasc website.

Thanks for the tip MK42gunner, popped over and satisfied my curiosity. Most one and two cavs switched to Lyman marked mid to late 50s.
