The 1903 Springfield uses the Weaver #54 in the rear and the #55 in the front.
The 1903-A3 uses the #59 in the rear and the #45 in front.
The Mauser M-98 uses the #45 in the rear and the #46 in front.
They no longer list a set for M-93 Mausers.
Now with all that said, you will probably find you will have a better result using the Leupold and Redfield bases.
They have windage adjustments and make zeroing easier. Many old military rifles were polished on slack belts and they look great, but are not concentric with the axis of the bore. Using Weaver bases sometimes makes them look a bot "off" because to get them aligned with the bore axis they seem crooked. With the Redfield and Leupold it doesn't matter as much because you can mount the base to look right and then use the windage screws to align the scope to zero.
I am a big fan of the Weaver system on most guns, but not on sporterized military rifles. I use Redfield and Leupold on them with much better results.
