Help! =20

For my 280 f4 APO lens, it appears that 3 screws are missing from the =
distance scale ring.  A fellow lugger has kindly examined his lens and =
stated that the two sets of screws in the APO Telyt ring and in the =
distance scale ring are identical.  Screw heads (slots) are visible in =
his lens and that they are about one thread into the body of the lens. =20

For the second time now, Leica has examined my lens.  The repair person =
said today that a new type of screw is being used, that it is recessed =
about 2mm (screw theads are clearly visible), and that it does not have =
a slot for a flat head screw driver.  =20

It will be most appreciated if anyone with this lens could take a look =
at the screws in the distance scale ring and indicate the type of screw =
used.  Are slots for a flat head screw driver visible?  Are the screws =
recessed about 2mm?  When you look in the screw hole, do you see smooth =
silver colored metal instead of the standard black screw?

Given the cost of the optic, I just want to ensure that my lens is =
complete.

Any input would be most appreciated.
