Yessir, welcome to the Forum, good info above and the call will be the way to go..... get the basic ship date....
as for the gun itself it is in the serial number range for the first, type 1 round gate, (1958) RSS5 ,meaning the loading gate itself is rounded on the back, easy to open...the other features should be a "dimpled face" ejector rod, and the steel ejector housing should be of the longer offset slot, we call it the long throw .....the later ones were a "straight" slot the whole length........
should be NO 'transfer bar' inside the rear hammer slot, telling you that it was NOT sent back and the "safety" conversion update was done to the gun, good selling/value point, and the grips should be the black hard rubber ( plastic) type, checkered with the black eagle medallion .........
sounds like a good gun, nice model to have, and any pictures would be great to see....tells us MORE of what 'Ty' said, "condition, condition...." and thats what the true value , worth will be determined, bottom line that is a $300 plus value gun, MORE if in mint shape, MORE if you can come up with any of the box, paper work, etc............ :wink:
