Found this old Berger in a cabinet today. I googled the model number with no success. Anyone familiar with this instrument or how to find any information about this model?
Think the model series is actually 65, according to this document.

Hope this helps.?ÿ You helped me kill about 20 minutes of a very unproductive day, so I thank you for that.
Definitely a 65 series. I was trying to date it but I haven't been able to locate any records beyond 1955, which apparently is around the time that the Berger sons sold the company. If I had to guess I'd say that it was manufactured in the early to mid '60s.
It looks like it's never been used, amazing condition.
