I am trying to find out if a frame stamped CB31-9860 is a 1954 goldie frame as the seller is telling me.
Goldie CB31 frame numbers from this year started at 101 and I am doubtful if they made 9000+ in one year.
Frames for a 1955 B31 were also stamped CB31 but they started at 6001 which seems more likely and they are not made of the same metal.
does anyone have records of frame numbers or any suggestions. Thanks, Neil in oz.

If you go to www.britbike.com direct and select Identification under BSA info and then 51 to 60 you can see more than just the Goldstar, that suggests that the frame like you say is not a GS frame and not a 54, nearest it could be is a B32 all alloy competition frame which are sometimes referred to as Gold Stars by the generation that could have bought them new.

Just to clear up any doubts.
Gold star frames were made from the same metal as B31/B33/A7/A10 frames
Gold star frames were dimensionally the same as B31/B33/A7/A10 frames
The only differences were details like lugs and the fact that the twins didn't have the kinked cradle tube


BSA B31 500 "Stargazer"
Greeves 200 "Blue Meanie"
Greeves 350
Greeves 360
Suzuki GSX1100 EFE "Sorcerers Apprentice"
GM500 sprint/LSR bike "Deofol"
Jawa 500 "Llareggub"

Hi Neil,
Does the frame have lug on the front of the headstock for a steering lock?
If it has, its another reason to support the belief that its a B31 frame
I would agree with the CB32 for 54 GS
1953 swingarm frames are quite different to the 54 version, an easy giveaway is the solid "kink"
forging fitted into the tubular frame rail

Answers to this as well as all the other questions you may not realize you should ask, and check for yourself no matter what a seller tells you, before spending money on a Gold Star are given here. Full disclosure: I am on very friendly terms with the author so this isn't an unbiased recommendation.

I was so shocked to read this that I immediately checked with the author to see if it were true. He was equally shocked and assured me he's been keeping pretty busy with other things and that if there is ever a 6th edition it won't be for more than a year. If then. He also pointed out that it's more likely his 'Compleate Gold Star Shoppe manual' will appear first (but in my opinion that's not going to happen anytime soon).

Is there a differance in frames re arc welding or gas welded. I was once told that the B31 A7 frames were arc welded but the Gold Stars were gas welded. I have a Gold Star replica made from various models and years with a gas welded frame but a B31 number. Any clarification on this please.

John: How are you so sure that you have a gas welded frame? I looked at several frames, GS and B31, and find good and bad welds, various types of beads, blobs of bead for tacking on bits and some splatter on all of them.
