Any ideas who might have rebuilt this coil?

I was sending some water pumps off to Skip Haney and thought that I would look at my coil to see about sending it at the same time. I took it off and it had three 6s around the bracket bolt hole. I talked to Skip and they were not his markings and he had no idea. He didn't think it was a good idea to send that one as he was not inclined to work on something that had already been done.

It looked to me like the coil has a newish cork gasket and non-original rivets and wire connection posts. It also had a crack in the side. I sent Skip a spare coil that I had for rebuilding, but was curious as to who, if anyone, might have rebuilt the coil that was on the truck? It generally starts right up and runs great, but I figured a coil redone by Skip is always a good idea.

Do those markings look familiar to anyone?
