Is this an early coupe expansion tank?

Keep on going through boxes, found this one, it could be from the “race coupe” that I was building.

Any information would be appreciated.

Looks to be in great condition and the correct item.

Should I keep the expansion tank? My road CS has a plastic one.

 

[rsporsche]

yes ... or sell it to me (or sfdon)

I think I will keep it, as the plastic, well, it is after all just plastic, thus finite.
The other, is a solid chunk of brass.

Thank you for the kind comments as always.

I would take it down to the original brass. I did that on my coupe. Steve Hose put me on to it. Not everyone's cup of antifreeze. My Bavaria has a B35 motor, so I will leave the plastic tank plastic.

I originally had the painted brass tank in my car (OE setup for a 2800 - I think).
When Don had my car, I had him install a different brass tank. One that I earlier picked up from Murray (Bluemax). Don had a radiator shop refurb the tank and polish it up.
I like the way it ended up. IMO looks classy with the rest of the 'CSi Look' M90 that he installed.

Agree, it wasn’t too much work to take it to brass and it looks nice. Go for it!
