BSA B31 1949 350CC Rigid CLASSIC MOTORCYCLE

BSA B31 1949 Rigid. I bought this lovely old bike about 15 years ago from a local elderly engineer it was stored in the back of his garage for many years and I didn't realise until looking at the V5 that it looks like he could of had it from new. Although it's currently taxed it hasn't been ridden for quite a few years and was last started about 4 years ago, it's spent a lot of time in storage. I've not attempted to start it but it used to run nicely, I drained the petrol tank when I stopped riding it and by now the crankcase will probably want oil drained out and everything else servicing/brakes/repairs etc. just a good going over, so no chance of riding it home. I'd describe it as tidy oily rag, use it as it is or rebuild it. Petrol tank is nice and clean inside and the chrome work is pretty good it's got jones wheel rims, there's a dual seat and BSA service sheets or manual included. It kicks over and has compression so probably wouldn't take a lot to get going, it's a fun bike to ride. Only selling as I'm giving up my workshop.
Study the photos or come and have a look, I'm in Richmond North Yorkshire DL10Sold as seen, ask questions no returns. Bank transfer on collection
Wheel rims are both Dunlop not Jones.
I've just found a single seat that mounts to the rear mudguard and what looks like a spare oil tank that can go with the bike.
