The Star Model BS was a continuation of the 9mm Model B with a magazine disconnect safety added. Made from 1968 to 1974. Except for several hundred slapped together in 1986 when Star was in dire straights. They scoured the factory for any and all parts they could find to assemble complete pistols. The one shown below is one such. It has a hole in the left side of the frame near the butt for a lanyard ring, so this frame was probably from a military contract. The slide has the forward slanting serrations and is the same design that was used on the Star Super B pistols which had a different take-down feature. The Parkerized small parts were probably made much later than the slide and frame. These late production Star pistols were flogged to Interarms and sold at discounted prices in the US. This one was in the stuff that I got from Dave; it wouldn't eject a case properly when I got it although it appeared near new except for scratches around the extractor retaining pin. Which might explain why it had a Super B Syrian Army contract reject slide on it. Which was a clue as to where to start looking for the problem. Which turned out to be insufficient spring tension on the extractor. Which I fixed by putting half a no. 7 shot ball under the spring. Now it works perfectly. I had it out today to test fire some reloads. It didn't gag once.
