I have several 992b's and 950b's and there are 3 different case screws scattered among them.

Flat head, and oval (rounded top) head, and a more rounded, higher polish one.

One 950b has Flat head, one has rounded highly polished. My NIB boxed 4c 992b has these rounded highly polished screws.

My 992b's have the oval heads and one has the flat head screws.

Anybody have a reference point as to what was used when from the factory? Opinions ?


Thanks, Charlie
