old World R Oregon City OR. Made in Italy. Fits a .45 i Think a 5 inch barrel but the gentleman i got it off of had a regular 45 colt series 70, The barrel stuck out about 2 inches. it would fit numerous sizes open end. He was a Retired officer. # 24337. The leather holster and the double clip holder is nice. the strap shows a lot of wear, i think its needs replacement. I thought i would send it anyways could make a pattern. Any Questions just email and Thanks For Looking.
