Pecar scopes were imported to the U.S. between 1954-1961. Made by Koehler of Germany, these high quality scopes featured an interchangeable reticle which was praised by none other than Jack O'Connor. The two scopes you mentioned are 26mm steel tubes & have the following dimensions; Pecar V-IS 3x7(1959-1961) 12.2" long & 13.0 oz. Pecar V-IIS 4x10(1959-1961) 15.7" long & 15.0 oz.
Depending upon condition, the 3x7 value is $200.00-400.00 and the 4x10 value is $250.00-450.00. I've not seen any as of late for sale on Ebay, This would be a great scope for that period appropriate rifle project. Hope this helps.
