L.A. Jensen in Lake City, FL., was a one man manufacturer who produced a replica Spiller & Burr in the early 1950's. He produced it in .44 cal. in order to not be confused with the original. These were of excellent quality. Many were sold as cased sets. Only five of these revolvers have surfaced as of 2021. L. A. Jensen made the very first production replica in 1952 and it was all American made. There were fewer than 100 produced and were the very first replica revolvers produced. They were produced from 1952-1960, predating Navy Arms by some 8 years As previously stated, they were in .44 cal rather than the .36 cal as the original Spiller & Burr.
