After all, it is 0.04mm per pin, not 0.4mm. Only 19*0.04mm off for a 
40-pin socket, and this one was smaller, right? Maybe you would notice 
the 0.76mm difference for a 40-pin socket and chip.

Maybe the ignorant could just dismiss the difference as Soviet 
tolerances :) Rumour has it that Russia redefined the railway gauge, 
extending the track width by 3mm, because it was cheaper than rebuilding 
all tracks after the collapse of the Soviet Union.
