Thanks again Cinch (and others)
I did a bit more investigating and looked at some other pics my sister sent. In those, it's easy to see the little initial on the bottom is in the right position, the heat ring is unbroken, the "7" is the right size and the handle shape is correct to the period.
It's a Blacklock/Lodge from early 20th century. Perfect fit for my Grandma to have purchased it before Mom was born.

PS, I've got to stop looking at those websites or I'll have another money sucking hobby going.
PPS when I get back to my trailer I've got to look into identifying an unmarked lid that fits my newer Lodge pan. That should be fun, there's plenty of info on the net for that even.
