Looks like a quality unit, but not like other Jaegers I have seen. The one I owned was stamped on top of the barrel, Jaeger Jenkintown, PA.
This.
I think of Jaeger rifles as being built pretty strictly in the English style, so the white-line spacers are a little bit off-key for that. So is the bolt. For one thing, I'm pretty sure that the bolt handle is a style that was designed by Leonard Brownell for military Mausers. Also, most Mauser bolt shrouds have a safety and yours doesn’t--I think it’s from a post-war Interarms Mauser. That’s not a bad thing, just odd. I think your rifle has a Timney trigger with the safety incorporated into it, so that particular bolt shroud makes sense. The trigger would have been added in the 50’s or later, and the shroud was probably switched out when that was done.
There is nothing wrong with Jaeger mounts. They’re not as common as they once were, and unlike a lot of other similar systems, they use split rings that will accommodate any modern scope with a 1” tube. The rings and mounts are probably worth $200 by themselves if they’re in good condition.
The upshot is that you have a very nice rifle on a genuine Mauser action chambered for one of the world’s best general-purpose big-game cartridges. The woodwork and metal work are both very nicely done, with some very nice touches like the cross bolt.
$600 was a steal for that.
