I can't prove a negative, but I don't see any thing that makes me believe this rifle is Paul Jaegers's work. Granted, it has a Paul Jaeger scope mount, but they were a pretty popular mount retailed separately by Paul Jaeger for Installation by others. Plus, the installation of the mount doesn't Show the workmanship expected and I never had the opinion that Pauel Jaeger was bashful about distinctly marking their work.
