Bar id help

[Woodslasher]

I’m going through my bar hoard in an attempt to organize it but I’ve run into a problem. There’s two bars whose mounting patterns I can’t id. One’s an old Windsor bar that came on my 048 and an old Oregon bar from somewhere or another. If anyone can tell me what they fit, I’d really appreciate it.
P.S. I know the Windsor fits D025 studs, but I think it’s been modified to fit those and I’d like to know the original mount pattern.

The Oregon bar looks like it would fit the large frame McCulloch saws which would mean it also fits a number of Homelite models. What is the width of the slot, will it fit the 3/8" bar studs?

The slot is 3/8, approx. I guess that means I have a 20 inch large-frame Mac bar.
