Yes of course! This is the company that I refer to as “RPB 2.0”. This is not the same company as “RPB INDUSTRIES” from the late 70s early 80s. This “RPB” is “Russel’s parts Bin”, Russel Weeks’ business. They were the early distributor of Masterpiece Arms guns. The earliest masterpiece arms carbines are featured in that catalog and they are stamped “RPB 45 carbine” on the side. Some of them were erroneously stamped “RPB 46 carbine”.
