This may be a stupid question, but have you googled any words or numbers on it. I've had good luck entering serial/model numbers and "Spotting scope" or whatever I was looking up.
It is a spotting scope. It's 20x. Everything but baush and Lomb and city of manufacture are in Hebrew. I have googled Israeli baush and Lomb spotting scope to no avail so I figured I would as the brain trust here.
