Hello my friends! I need your help identifying an old Otto Link metal 5 MPC. I've had it for over 30 yrs and played it all thru High School and College. After that I became a diehard Vintage Levelaire Player(with slight mods). It doesn't have the USA stamp on it & one of my buddies seems to think it may be a Florida piece. It's exactly 4 inches long and does not have the gold plating. It's been so long ago, I'm not sure if it ever did, but possible. It sure doesn't look like pure brass stock either, it's actually silver in color. I'm a freak about keeping my equipment mint and this is no exception. But I do notice on the side of the actual biteplate some metal is showing thru?? Seems odd, but I've always used a rubber cushion on top by habit & comfort. You guys are the best to ask,...so I'm asking!
