Hello - I am looking at what I think is an early model IFRAME. All the serial numbers match except for grips which are fake pearl. the number is 468191 preceeded by a star on the bottom of the grip frame. The same number is under the barrel , but it is preceeded with a B inside a diamond shaped square. There is a small trademark on the left side. There are 4 screws on the side plate, one screw in front of trigger guard and one on the bottom front of the grip frame. the barell is 3 1/4 inches. The grip frame is a round butt, but the grips are adapted to give then an extension and turn them into a square butt. Last patent date on top of barrel is dec 28, 14. 32 LONG CTG is on the right side of barrel. After taking grips off there is a 30 stamped on the left side where the grip frame meets the gun body. on the bottom just above the grip pin is a B inside a diamond shaped square. on the right side of grip frame, in front of the grip pin is a H with a B stamped underneath,. any info on this gun would be greatly appreciated . Thanks in advance - Bill
