Vintage Motorcycle Tank, Benelli, Ducati, Gilera, Riverside

I'm selling my vintage Ducati spares, including this tank, which is actually from a Benelli 250. It's in its original paint which matches one of the schemes used on the "Ward's Riverside" models, however there is no evidence of emblems showing it was a Riverside bike. Instead, I think it was direct from Benelli. I purchased it as a possible fit on my Ducati 250 as it's a great looking tank. There are two dents in one side, as can be seen in the pictures. The inside could use a clean/descaling, as these old tanks often need. Any further questions please ask, and thanks!
