BSA A7, longstroke, petrol tank

[Johannes]

Dear all,

I have almost finished the restoration of my A7 Long stroke (1950). I spend a lot of time and money. Now, I've got a serious Problem. I send the original Petrol tank to a Special Workshop for inside cleaning and coating. Unfortunately, the Company lost my Petrol tank!
I would like to start up the A7. Therefore I've assembled the Petrol tank of my B33. However, that is Only a temporary solution.
Does the Petrol tank of the Plunger fit to my rigid A7? I can get one from a 1953 model and here are some at eBay from India.

Best regards
Johannes

Bad news Johannes. I hope you hurt somebody. A lot!

That's really bad. How the hell does one lose a petrol tank...!? 
By the sight I would say that an A7 plunger tank wouldn't fit. Your cylinder head sits to high up. The bottom of the tank would hit the rockerbox I think. An A10 plunger tank would be a better bet as it has a deep recess underneath to accommodate the higher A10 cylinder. The mounting holes are the same on both A7 and A10 so that should work.
I still have my old A10 plunger tank which is sound but has a nasty dent on the left and a hole on top where the PO installed a breather pipe. If you are interested in it PM me, maybe we can find an arrangement.
