J Unertl Vintage 6X Rifle Scope With Mounts, Price Reduced

Vintage Unertl scope, 6X, one inch steel tube, 1.5 inch objective lens.  Clear optics with fine crosshair.  The front base screw works smoothly, the rear screw is stiff.  The front mount has been slightly modified, shown in photo.  The scope ring clamps are .310 and .440 inch opening for mounting blocks.   Reference from "Old Gunsights and Rifle Scopes" by Nick Stroebel.  Plus you can check pricing and variations in USD on Ebay.  This would look good on many ca.1940's-50's rifles.  USMC used a similar item on sniper rifles in Korea and other places, most famously apparently by Carlos Hathcock in Vietnam.  The scopes you find with the 'spring' were an option put on at the factory.  Mailing included in the price.
