Is this a milsurp scope?

So walked into a gun store on my travels and sitting there was a scope and mount that stated they were for a K98. The picture of the mount didn't turn out but it's an LSR type that mounts to the side. I can't say for sure if it's a K98 mount though. On the underside it looked like a groove with "teeth" inside? I've never seen a K98 LSR mount in person. I didn't see any marks except someone scribbled an number on the bottom with an engraver type of thing. That being said the patina seemed to be the same as the scope.

The scope was variable. If I remember correctly the three marking were 3 3/8, 4 1/2, and 5 1/2? The glass was REALLY clear as I looked through and moved the variable.

They wanted $430 for the scope and the mount. I can't find any info on the scopes though and don't know if the mount is actually for a K98 or not unless someone can post a picture of the bottom one for me.

Here's the only other picture of the same scope I could find online:

The rifle was being auctioned off. It's called an "Engraved Hermann Weihrauch Marked Custom Pre-War Model 98 Bolt Action Rifle with Scope". The rifle and scope sold for $3500 USD.

Here are two scopes being listed as WWII sniper scopes with the supposedly original scope cases:

This site lists it as WWI vintage:

From what I read; Between 1926 and 1929 the Carl Zeiss company bought the majority share of Goerz and a few other companies. They bought up the companies who produced good lenses. So for awhile all lenses/scopes/binoculars/etc were marked as the original company name and said Zeiss.

Eventually Zeiss forced these companies to stop making lenses all together under their own names and were forced to work strictly for Zeiss themselves.

This scope does not have the Zeiss name/logo anywhere. So this would have to put the scope sometime before the takeover by Zeiss or very shortly after the takeover and before Zeiss forced their name onto the optics.

But from what I've been told there were no variable scopes before the late 40s or early 50s.

Searching online brings up people claiming it was made from 1920-1930, others claim 1930-40 and others claim 1940-50 and some claim these scopes were made even later.
