Litschert was known, back in the day, for making a power boosting attachment for the low power scopes of the day. I believe you had to send whatever scope you had to Litschert, and the attachment was permanent. Many benchresters and varmint hunters of the 40's and 50's used scopes that had the power bumped up with a Litschert attachment.
I was not aware that Litschert made a complete scope, but it sure sounds like that's what you have.
I don't know what the dots on your other scope represent. Dot reticles were very popular before the advent of the duplex reticle. I think you'll have to experiment to see what the 3 dots represent. They may have been factory installed, but maybe not. The T.K.Lee company installed lots of dot reticles of various sizes- whatever you specified. BTW, T K Lee is still around, last time I looked. They have done some dot reticles for me- they do very good work. I believe their website is:
www.scopedot.com.
Sounds like you have some nice old classics there!
