Post you late (1994 or later) IBM M 'F' & 'L' labels here ..

[Peter]

In the 'S/N' on a Model M-label :
'L' is for 'Lexmark
'F' is for 'IBM' ..
('Late' is 1994 or younger ..)

YES - The label is upside-down !!
So :
'Quality-control declined in the later productions-years ? ' = CONFIRMED !

I've never seen one, but there should be some with a '99 date-code !

Next, I would like to confirm that there IS in fact a difference between 'Lexmark' & 'IBM' of the period ..
So far, I don't see any, except for what is on the label !

Next to come :
I will disassemble 2 '94 or '95 Type 3 case Model M's, one a 'L', the other a 'F' !
