Hi George,
I will have a look as i had one of these and wasnt sure why it had the rubber grommet but no F mark- i just dont know where it went (likely sold, not lost!)
Here a pic of it from when i asked on the tech forum a few months back. I had kept it thinking it might be correct for my MB 131175, but obviously based on your TM info, it is not!
Click on pic for a larger version.




If i can find it, hows $40AU plus post sound? That is what i usually get for gas pedals- i`m not fussed this is an earlier one and want more money (as i didnt know its rarity before, so why should that change the price later!). I just need to find it and with holidays next 2 weeks, that should be easier to do.... keep PM'ing me until i let you know yay or nay!
In the mean time, if others have one, please pipe up for George as i cannot guarantee i still have the one pictured above.
Cheers,
Ian.
Ian Fawbert.
