Unknown Mauser K98 - Information request

Hello ! What's the exact model of this Mauser K98, as seen on a Swiss gunsmith web site (please see attached picture) ? Thank you !!!

Would need better pictures imo.

A 1934 Banner. Its on GB.

Appears to be a Spanish Model 44 Air Force. Some of these may have been rebuilt Polish WZ29s scrubbed and remarked. This is based on only 2 sling attachment points on the left side of the rifle. The rear one being a bar over an inlet like the French 98K reworks.
