The Norman-Ford Co. of Tyler, Texas introduced their Texan line of high quality scopes in the early 1950's. The 4x Texan was made between (1953-1958) and is 12.5 inches long & weights 9 oz. They offered both internally adjustable & fixed tube externally mount adjustable models. I had a 2.5x Texan once & it was tough, quality scope indeed. There is a collectors value to these vintage scopes. I haven't seen any on Ebay lately & depending upon condition, are valued at $75.00 - $150.00. Hope this helps.
