I've removed this from my Avon rib as it was getting a bit cramped, as you can see from the photos it's not in fantastic condition being original to the boat. It has a hole in the bottom as it was used for battery storage and has a cable gromit on the back and a vent grille.
Bench Seat (BS10)
It's simialr to this one in the outhill catalogue, as you can see rather pricey!
For this reason I'd not want to take much less than £250 really.
I'm based in Exmouth but regularly travel to Bristol so I could deliver if I'm not going too far out of my way!
