1981 Ocean Yachts interior teak coating?

Hello, I have an '81 42' ocean sunliner and I'm trying to figure out what the factory used on the interior teak trim and bulkheads. It seems to be some sort of varnish/stain combination. I've tried interlux satin interior varnish but was too glossy and clear. Seems to be an old Pacemaker/Ocean concoction the Leek family made up?
Any ideas would be helpful.

I had to look up tongue oil, heard of it but didn't know how it works. After looking over some short "how to" videos, I don't believe that's it.
What ever Ocean used was applied with a brush and left to dry. I can see the brush marks along with darker and lighter sections. My boat was not Ocean's best effort unfortunately. Not sure if tongue oil could be brushed on and left to dry? Must be rubbed , right?

Boomer!! ..lol, yes I'm pretty sure no one did along the way. All of the finish matches up through out the boat , including the hard to get to and see areas behind equipment and built in stuff.
I'm just trying to fix up some scuffs and scratches. Also blend in around the forward three windows , I'm not looking to re-do the interior.

Yes , That's what I think Ocean used on this in '81.. some stain/varnish combo , to speed up production time. Funny, was at the Hardware store in Cape May this weekend looking over that minwax combo stuff...in satin. I'm going to take a drawer /door in from the boat to match up to the minwax wood treated samples.
