They were an early clone imported by EMF. I owned one several years ago. It was a tri color, nickled frame, brass grip frame and the rest blued. 100% floral engraved, it was beautiful but apparently copied too closely after the early Colts with oversize cylinder throats. This gun measured .458 to .460 and would only pattern even with oversize bullets. The barrel was .451. I bought a .45 acp cylinder for it that had .452 throats and it shot beautifully and to point of aim. I thought about boreing that one out for .45 colt but it shot about 8" high at 15 yds with .45 colt and would still need a taller front sight. It just seemed too much work for the results and I sold it. Now I wish (like so many times!) that I had kept it and put the work into it. It had an axle spring for a main spring but that was common back in the 70's. It was a good gun that just needed some work. I hope you enjoy yours. 44 Man
