BA7S is a plunger frame number.

Hello are you realy shure?
Framenumbers with BA7S ended with Number 20289 in 1957.
I thought always the last plunger was made in 1953, then introduce the Swinging Arm frame with model 1954.


Thank you for your helping hand.

Cheers
Klaus

This list shows only A10 Plungerframes where made up to 1957.
There is no listing for A7 with plunger after 1954.

I've heard plunger bikes were favoured for sidecar use so maybe that is consistent with bsa only making a10 not a7 with plunger frames after the swing arm was introduced  *dunno*

But it's not always possible to tell if a frame was originally for an a7 or a10 purely from the frame number without consulting the despatch records as they are generally all prefixed "xA7".

The VMCC UK can also access the bsa despatch records, and provide certificates, I'm not sure if they own the records or the bsa club.

I understand the VMCC got there data from the British Library when it ran out of room and that the BSAOC got theres from the factory when it closed ,they had close links with Alistair Cave ,who I think, was  works manager at small heath and He may have had something to do with it ,I do know that there service(bsaoc ) is second to none, Bob

Hence my question to the datingmanager.
This bike is also stocked with Acront Alloyrims I gues it was customer wish. The Tank  wear a 4 inch tank badge with the Goldstar.

Klaus, I think BSA were quite unique in there build and supply policy . It seemed to be that something was discontinued but could be obtained -if the right person was asked or a good connection exited ie over here the AA wanted there outfits as they had always been made  and BSA supplied even though that model had been discontinued yrs before . If they found the parts they could build 'em and did with whatever was to hand hence a lot of the weird things that we all come across  . Not economic sense but that's the way it was explaine dto me by people who were in the trade then. Bob

 Screen shots from Spares book '54-'57; pages 2 & 32; P. 2 clearly includes A7 Plunger models, P.32 ("Plunger frame 'A' Group") doesn't specify A10 only, or exclude A7, so what Kiwi and Topdad say may well be the case

Maybe, just maybe, someone has restamped the frame? A swinging arm frame from that era should be CA7. No "S" suffix.
I would be very surprised if any A7 or A10 came out of the factory with alloy rims in 1953, Akront or Dunlop.

I agree with Trevor; a 1953 swing arm frame, yeah right! with a plunger number . sounds like a number job to get a bike past the bureaucrats or police.
A lot of things can happen to a vehicle in 62 years.
I was shown a genuine unrestored beesa recently with the original tank paint... until I mentioned I'd owned it and repainted it 5 years ago. Small world but sadly not everything is genuine out there.

How about a picture, still sounds like a nice bike!

The easy and right  way is, to ask the BSA records. Ok there will be somthing strange and unexplicable, but l am shure that this frame is not restamped.

I have a A7 crankcase with enginenumber  DA7 5123 the 500 cc had never the prefix D.
It will be a good opportunity to ask what about.

I will tell what the records say.

What's going on in Germany?

Hi Trev,

some parts are from the USA.
It'srealy hard to find A7 or A10 stuff in Germany. These are very expensive so it is cheaper to get parts from overseas despite duty around 20 percent.

So the question had to be.
What's going on in USA *smile*

cheers Klaus
