Need some help with J frame stock ID

[mod57]

I find that I need to buy a set of RB J frame stocks for my ‘91 vintage model 60. To be sure there are a lot of them out there but I want them to be correct in appearance. I assume I need the type with the stainless steel stock circles but I don’t know what the checkering pattern looks like. I am told they were changed in circa 1968 and then again in the ‘70s. Anyone got any pictures of what I am looking for?

These are not mine, just a picture I found on the internet. This is what came on the model you asked about. They were usually finished with a glossy Urethane or similar.
