WELL FIRST OFF THE G2 HAS NO ENGRAVING ON THE FRAME THE NEWER CONTENDERS HAVE THE LEAVER ON HAMMER. IN CHECKING YOUR SERIAL NO. IT SEEMS TO HAVE BEEN MADE IN 1994 BETWEEN JAN. AND JUNE. ALSO THE GRIP AND FORE END ON G2 WILL NOT FIT THE OLDER CONTENDERS OR WILL THE OLDER CONTENDER WOOD FIT THE G2 BECAUSE OF GRIP ANGLE AND ALSO THE ROUNDED BUMP OUT ON THE G2 FRAME. HOPE THIS HELPS. THERE IS ALSO A LIST OF SERIAL NUMBERS AND DATE OF MFG. ON THE FORUM THAT WILL HELP YOU IN FINDING OUT HOW OLD THE GUN IS I CARRY ONE IN MY WALLET AND WHEN I FIND ONE AT THE GUN SHOW I CHECK TO SEE HOW OLD IT IS.
