1920s BSA Flat Tank

Unread post by Backstreet Mechanic » Tue Mar 24, 2009 7:02 pm

I have various boxes of bits that should make most of a 1920s BSA 350 OHV Super Sport. This seems to differ from the other BSA OHV 350s of the mid twenties by having a seperate oil tank with integral foot operated pump below the seat. This negates the need for an oil compartment in the fuel tank so the Super Sport had a one compartment tank with single filler, probably unique to that model. I have the correct tank but it is in appalling condition, very rusty and numerous holes. It is debatable wether it is restorable or not but it would act as a pattern for a replacement. Does anyone know if there is a specialist in the UK who can undertake this sort of work? I remember Rick P having a go at making a tank for his Rex and having to admit defeat, If he cant do it I am pretty sure I cant. I do remember an article in one of the classic mags about a guy manufacturing tanks I think in Scotland but of course cannot now find the article. Any help/suggestions much appreciated. Mike

Try giving these people a ring, they specialise in car panels but may be able to do a motorcycle petrol tank.

Hi BSM, your best bet is to completely give up and sell the bike to me. It is clearly a hopeless case...oh alright then, no I didn't give up I got there in the end but it was a bit of a palaver. I don't know whether John Williams at the Tank Shop would do the job, he mostly does alumium. He's worth a call but he is very busy so get in early. 1927 Super Sport is without doubt THE BSA to have. Good luck with it!

Thanks Rick and Jimmy yes I am sure it was The Tank Shop featured in the article I will give John Williams a try.
DAM mphmotorpanels looks interesting, I have massive respect for Aston Martin panel beaters having toured the original factory in Newport Pagnall a few times in the 70s. I do fancy trying the wheeling course that they are advertising looks good value for money knowing the background of the instructor.
Rick do you know what the prefix letter should be on a super sport engine. I know the Side Valves are F and the OHVs L but not sure if the L applied to the super sports as well. Mine has a primary side crankcase half with an L prefix but I stongly suspect this has been substituted at some point as the 2 halves are not a pair and the number would suggest 1926 which is too early. The top end has the distintive sloping push rod tubes which match the super sports in a 1928 brochure I have and the engine was with the correct fuel and oil tanks supporting this model. Thanks Mike.

That's about when my father worked at Aston Martin.

I am planning to try that wheeling course some time, I have an english wheel and a fair bit of associated tooling stored away that I cant use until the new garage/workshop is completed.

A couple of years ago a chap called Ray Petit in Nottingham did two tanks for me.. they were brilliant. I don't have his address and phone number to hand but I will try and dig it out. He was very reasonable and the work was faultless.

The VMCC have the factory records but there are a few books missing and it is in a hopeless muddle - some of the books are by frame number some by engine. I have a sheet I copied from a 20s pitman book years ago and that says 1927 Super Sports is engine D100 to D654 and L6501 to L8408. Frame numbers for this series are Z9474 to Z13981. It lists the sv 1927 as F14000 to F16679. Bit vague but that's the best I can do.
Terry Baker in Wales is suposed to be very good for tanks.
Cheers Rick
