PURCHASED A 44 HAND EJECTOR BEFORE I HAD A CHANCE TO RESEARCH IT OUT, AND NOW I DO NOT KNOW EXACTLY WHAT I HAVE- the serial number is 15519. It is located on the butt of the gun and on the cylinder. It has a 4 " barrel and aftermarket bone grips that have turned yellow with brown grain. It is NOT a triplelock but it does have the barrel shroud. 44 S&W SPECIAL CTG is on the right side of barrel and SMITH & WESSON on the left side. 736 is on the yoke. I see no patent dates on top of the barrel nor do I see the S&W symbol on the side. I am sure that it has been refinished at some time. the gun locks up tight- no rust or pitting. gun came in an old holster made by STELZIG SADDLERY CO., HOUSTON TEXAS. Pictures will be sent as soon as I return home to my camera. the serial number says early 2nd model but the configuration says Ist model but without triplelock- could this be a transition gun or what. thanks - bill
