Now we are getting into very deep detail, but the very first Argentine LT bases didn't have screws at all and were only soldered. I own the 39th Argentine scope ever made, with its original bases. Looks like that:
Note the scope doesn't carry any Zeiss markings at all, all markings on the tube are hand engraved. More pictures on the thread I made on it back then:

Edit: that AR to my knowledge is a French firing proof. Note the barrel is marked 8x60 atop, back when 8x57 was prohibited in France the rifles got their caliber converted to the 8x60 to make them legal.
This whole thread is a bit weird. The images posted in here are only very detail aspects with none showing a full item. But thanks for Xavier to show the rings posted originally were not always with the scope it is now. Maybe this was the "restauration" that OP
@sauer spoke of? Given that the base somewhat looks like it is an Argentine front LT base (again: no full pictures visible?) maybe someone pulled them for the whole rifle being a fake. That would also explain the weird stamps on the rings. So maybe not an "early low turret sauer" but someones enhaced Argentine LT set?
