The correct C3 (elect.) speedo for fitment with 50 series tyre (M395 option) is '930' 641 501 00
There was a specific mech. speedo built & calibrated for factory fitment if M395 option was ordered on a 76MY C2.7.
The unit that would be fitted by the factory 'IF' a 76 MY C2.7 was M395 optioned , would be no. 911...641 530 00

You are correct Ratbox force of habit of putting 911 as first digits of part number.
I note the 911 641 530 00 is shown in the '73 parts catalogue as for 50 series tyres but does not appear in the '74 to '77 version.
