Is this a Weatherby XXII Magazine?

I need help identifying this old 22lr magazine.

I looked at all the Weatherby magazines I have and none look quite like that. But the metal and base plate do look a lot like the Beretta .22 magazines for the Olimpia/Sport/Super Sport. So since Beretta made the first Weatherby rifles, it may very well be a magazine for that. What does the magazine catch area look like? A square cutout? A filed line in the metal?

Thanks for the reply. The mag catch is just a very fine line.

I looked at the Olimpia magazines but they don’t have the same long cut away. The slotted screw looks original and could be a clue. The mystery continues...

Doesn’t match any of my Weatherby mags

Looks somewhat like a berretta mag, but definitely not the OEM weatherby XXII. Mag retention bump out or square cut out is not present. Maybe a Triple K 847M?
