What might these fit?? (scope bases)

[Potashminer]

These two bases appear to be a pair, have no markings, and were in a bag of scope mount bases from an estate, so I have no idea what they might fit.

One has a curved base - I am guesstimating 1.5" diameter - larger than a Mauser 98 front ring since it rocks slightly when set on an unmolested Brazil 1908 receiver. The two holes are .322-.323" centre to centre, oriented conventionally if it goes on a front receiver ring.

The other has a flat base. It has two holes about .503-504"" centre to centre, that would be at right angles to the rifle.

Laid upside down on a flat surface, the peak of the curve on the first one is the same thickness as the flat on the second one.

I note that they are not perfectly symmetrical, so they are possibly "home made", but I am not familiar with a rifle with a 1.5"-ish diameter receiver ring, and rear scope base holes at right angles to the bore line.

Anyone know what they might be for?

Bubbafied p14, p17 or even a ross?, but this is just a guess. Did somewhat similar hillbilly engineering on butchered rifles.
Be well

Winchester model 94 big bore would be my guess

They look homemade and I'm thinking p14 m17 or ross too.

They look like they would fit a 94 big bore or angle eject as well, good guess!!!

Model 94 AE

The receiver on a 94 big bore is only about an inch so the rounded one would be way to big at an inch and a half. The workmanship is crap. You can plainly see they were made with a file and drill press. They wouldn't fit my big bore or AE 94's as the bolt itself is over 1/2" wide so the holes wouldn't even reach the receiver on the sides.
