Thank you for all your replies and kind help.The Rifle in chambered in 6.5X55 Swedish.I bought it close to Norways boarder with Sweden.
There is a replaced segment on the stock to the right side of the receiver and two very well done (almost undetectable) plugs in the right side of the receiver.Suggesting perhaps that it once sported a receiver mounted sight.There was a discussion on another forum regarding this rifle,I dont know the rules regarding linking to other sites so I will just say they concluded the Rifle was made in about 1919 by a company in Efurt Germany.The serial numbers are consistant through out the Rifle,Floor plate,bolt,receiver,safety etc
I like Southerns suggestion of simple mounts but I really lean towards detachable mounts due to my desire to hunt Reindeer and that can and does involve snow storms which can render scopes useless in moments.Whipping of the Scope and using Irons is a advantage,even with Roe Deer hunting in Sweden when the weather goes from mild to wild in a short period of time.There are two holes on the Barrel that have screws in them I will use to mount a rear sight,I have one suitable in my box of "treasures".
The bore is in pretty decent nick,a bit of frosting on the lands,the proof is in the shooting.Its just a nice old Rifle I will use for hunting at medium ranges.I paid about £250 for it.
Could hardly see it for the engraving, but yes, it's a small ring mauser which therefore might make it an erfurt, still, with an interarms bolt most likely. You'll therefore have, I suspect, a small ring large shank barrel as most erfurts I've seen were large shank.
the cutting and filling on the RHS of the stock is quite large, might have been accidental damage and stock splitting that happened when it was inlet for a side mount on the RHS, as there were not RH sidemounts used of that magnitude. The oversize repair job was most likely to ensure all ends of the damage were secured from further 'runs'.
No leupolds are not reliable for return to zero, talley are within 1 moa but still not good enough to rely on for smaller game with more precise shot requirements. pivot mounts are pretty darn good from eaw and recknagle, and perfect fit clawmounts are the best by far..but, as with ALL QD mounts, you simply cannot and should not rely on them to A. always keep zero, and B. Return to zero.
In my book, QD mounts are for removing scope when really necessary, and once scope is re-fitted (at least on bolt action CF's'), you should expect to control shoot it to check zero.
For DG hunting, it is of course well known that the QD system should be removable very swiftly and only using one hand whilst holding the rifle in the other and getting ready for a shot..you may be in a hunting situation where having to fiddle with levers on the wrong side of your dominant hand or multiple levers is nothing but dangerous.
The ziegler kontramount is well made, but personally I find it very ugly and also the scope tips backwards, so with a big bolt shrould like that on a classic M98 (domed), you might find that the bolt has to come out before the scopes ocular bell housing can tip down far enough,,and to me, that's just a complete joke and a no no no area.
Best QD mounts I've come across are the one's built into DSB's by Joe Smithson, esp. with the single release button on the rear ring only...that said, just the rings are about a grand in the white
