Nice rifles.
They attribute the engraving to (Kurt?) Jaeger, Germany.
He had many engravers working for his shop including Emil & Claus Willig.

I don't see any mark on the first one with a quick look over.
The second one,,the .222. has the engraving signed (I believe it's the engravers mark) in the criss-crossed ribbons on the forward portion of the lever ahead of the figure.

I can't get the pic clear enough to read the lettering though.
Most all of the engraving from Kurt Jaeger's shop was marked as just that,,Engrv by Kurt Jaeger.
A few were allowed to be signed by the actual engravers like the Willigs'

Claus later came to the USA and did work for Paul Jaeger's shop in PA as well.

The Oak Leaf on the first rifle looks just the way he used to shade his on earlier work. But many engravers learned from the same 'school' and eachother. So some techniques and similaritys
are obvious.
