Sorry I know it’s not pre 1980. Could not find appropriate forum

G500 perhaps

G500 perhaps

The front cover and pneumatic adjuster say G500 to me too.

I'd tend to agree...

Picture isn't clear, but that MK20 may also still be under recall....

The photo is blurry. After staring at the MK20 saddle, it looks like the new one. I have to say thank you to all. A place to get opinions from knowledgeable people is priceless. Thanks.

2 vents is good, 3 vents is "questionable".... (the saddle was to be changed with the new retainer being installed, but occasionally was not done).
