Can I find period saddle mounts for this?
It appears you did not consider the most important aspect: for a claw mounted scope to be mountable on a K98k rifle the rings on the scope tube need to have a very certain spacing to be sitting on the receiver ring and receiver bridge. Secondly, even if this spacing is of correct distance, still the scope needs to be in a certain position as well for proper eye relief.
While I do not have your scope in hand it appears the spacing between the rings is not correct for a K98k receiver, it looks more your scope originates from a break barrel rifle since they are rather close to each other and mounted to the very front.
Secondly, even if the spacing between the rings is correct AND it would have the correct eye relief for the Mauser 98 action, the largest issue are the bases. They need to be of correct height to allow proper alignment of the scope. The rings on your scope look to be of approx. same height at front and rear. Since the receiver ring at the Mauser is higher than the receiver bridge at the rear and if you do not want to dovetail the receiver ring (since originally they use a saddle) usually the front ring is less high than the rear scope ring. You could "equalize" this by building a high basis at the rear, but this then puts your scope way too high above the bore axis, so you'll end up requiring to use a cheek raiser to be able to shoot it.
Finally, Suhler Claw Mounts were always hand fitted and hand made. It is extremely unlikely that you'll find bases which fit the scope rings on your scope. So in the end you'll need to get those made individually for your scope which means they'll cost you a fortune because if they are made by someone not skilled enough for those, they will not sit tight and you'll be disappointed by a bad mounted scope.
As a conclusion, the Suhler Claw Mount is the worst mount you can use to build a replica. I strongly recommend all to stay away from this mount, unless you have a scope not only with rings but also with (saddle!) bases with the correct height and spacing for a Mauser 98 receiver. And even if you have those, you'll still need someone who is skilled enough to properly solder those to the receiver. For a replica therefore a turret mount or a side mount is ALWAYS the one to choose.
