Hi,
I've a good set of cast iron BSA A7 Plunger barrells for sale. There are no broken fins - rare these days. They come with 2 pistons - but these would need replacing. No idea of bore size or if oversized - one of the pistons the barrells came with has 0.2mm O/S stamped on it - the other piston doesn't. If in doubt please ask via PM.
I'd rather they go to a forum member than use Ebay or Scumtree. Open to reasonable offers; will post at cost (assuming the risk is on you) or happy for collection (at a distance :-) ). They need to go as I no longer have and BSA's and have a new project.
Also I have a new rear sprocket for a A7/A10 Plunger - search ads for it or PM me. This also needs to go.
Cheers
