tlhelmer-the Model 547 was make in the mid 80's, if I remember correctly...seems like there was the four-inch square-butt version and the three-inch round-butt version...don't know about total production numbers, but they ARE seen OCCASIONALLY on the market...If I wanted one, I'd periodically check the on-line auction sites, peruse Gun List and haunt gun shows. I'd rekon the going price would be in the $300.00-400.00 range...the lower number for a very good to excellent specimen, the higher figure for one unfired and NIB. Good Luck!!!....mikey357?
