I had a 144LS that I purchased for around $65 new from Herter's back in '74. It was equipped with Lymans, which I removed, and slapped on a Weaver 4X for usage against nuisance birds and squirrels (food) at distance. I favored 50-100 yard shots with Winchester T22 target ammo. Very quiet out of that long, heavy, AccuGroove (8 lands and grooves) barrel, and as accurate and deadly as sin. In a fit of stupidity I sold it to an acquaintance because he was drooling all over it and practically got down on hands and knees begging me to sell it to him. (One of those "I regret I sold it" moments.) The Lymans went along with it.
I only see older 44s and the newer 144s pop up occasionally, going for $200-$400, depending on condition and completeness. I have been sorely tempted to pick up another one as they are more accurate than any of us will ever be. They are a great rifle.
