spent pressure vessels - any value?

[Fogg]

After 7 yrs the diaphragms failed in my expansion vessels, I replaced with the red type with a buffer which supposedly prolongs the life because they're better protected from hot water.

Anyway, I've 3x 1000 litre vessels which can be renewed with new rubber.

Is it worth trying to sell them, or are they scrap? WWYD?

Make a pig roaster.
Someone will make good money of them, might as well be you.

If one of them has a 1m wide dished end, I could do with a new fire pit…

I welded bolts on each end and filled both parts with water and tow them behind my ride on mower as a lawn roller.
