Correct spare tire compressor for 1978 Turbo
 

I am missing the original spare tire compressor for my 1978 911 Turbo (930)

Can anyone confirm which one that was originally supplied with this car?
Preferably ROW if there is a difference between US49 and ROW.

My search have led me to a couple of candidates:

Is this one correct?
