D and T hole spacing for a Large Ring 98 Mauser

I don't believe the rear receiver bridge is level with the front receiver ring.
The charger guides were either ground off or milled off. That trigger doesn't look like it's issue either, nor does the trigger guard, which looks like it may have come from a Portuguese Verguero.
The trigger change out could be a good thing and the hinged floor plate is a nice option. When the Vergueros were dirt cheap, it was expedient to purchased them for their hinged floorplate trigger guards and swap them out with a standard length K98 assembly.
That looks like a nice rifle. Sportered back in the sixties or early seventies. Someone took their time with it and did it right. I hope it shoots well. The barrel is also a replacement and the rear receiver bridge has been drilled and tapped for a micrometer adjustable sight.

Re-read Post #2. Scope base screw hole patterns were sorta standardized among makers. Your rifle may not be a "factory" conversion of a former military rifle - therefore whomever did the work was free to drill and tap whatever hole spacing came to mind. Important that the top of the scope bases form a plane - check with a steel ruler. If they are straight with each other, and if they are unaltered Weaver bases, each will have a number on them. Charts readily available to show what the design hole spacing was supposed to be for those bases. Quite often identical hole spacing and matching scope base height used by Leupold, Redfield and others. No guarantee that a one piece rail will fit - that required the distance from the front holes to the rear hole to be standard - whomever did up that rifle might have followed "standard" or might have done their own spacing. Same with the "grind" on that rear bridge to remove the stripper clip lip - might have removed more or less - might have required rear base to be shimmed or to be thinned. End result for almost all mount systems is the top edge of the bases need to be a plane - straight to each other, flat, more or less parallel with the bore line, when front and rear screws are snugged up.

Those Weaver base pairing are pretty much the standard for a Mauser 98. As per the Weaver chart (find on Brownell's site and other places), the front holes will be .860" apart and rear holes will be .504" apart, so most other two piece base pairs will likely screw right on. If the maker used standard spacing, the one piece STD base from Leupold or similar from Redfield might also fit - I do not have one on hand to measure the distance from front holes to the rear hole that it uses.
