Is the frame on the Rocket Gold Star the same as the one used on the A10

or do they put this twin cylinder in the Gold Star frame (with the 'kink' for the oil pump)?

It's not the same as an A10 and has no kink.

It is more like the 1954/5 A7/10 frame than the later ones.

The early A10 frames had the 'crinkle' rear hub and Goldie type swing arm but didn't have the four brazed cast engine lugs at the front. It's probably near the 1961 Goldie frame but without the kink.

I just today stumbled on this information from the Hagery site on a coming auction entry. Are they incorrect here regarding the frame? I had always thought it was called a Rocket GOLD STAR because of the A10 engine in a Gold Star frame? - or - an error by Hagerty / Mecum.

HI
Yes they are wrong with their description
The frame is unique to the RGS model
There are several detail differences between it and either A10 or Gold Star frames
They are very often forged or cloned due to the high value associated with the model
Supposedly there are 5000 or more survivors of the approx 1800 made !!!!!!!

Yes, they have it mucked up. The story goes that Eddie Dow had fitted Road Rocket / Super Rocket engines in Gold Stars for some of his better-off hooligan customers, and proposed the idea to BSA. The RGS was aimed at a similar clientele, and just conveniently happened to be a way of using components which were already on hand for models which were going to be discontinued. I was 5 years old at the time and on the other side of the world, so can't vouch for the veracity of this, though smile

The RGS frame is very similar to the late Gold Star CB32 frame, but without the kink. The very late GA7 frame is also quite similar.

Auctioneers will say ANYTHING to get bidders into the hall.
They rarely know anything about what they are auctioning, and do not want any knowledgeable person to contradict the false claims of the sellers.

They get a COMMISSION on the sale, so the higher the winning bid the sucker makes, the bigger their commission.

Two fast ways to get "escorted" out of the hall:
(1) Ask that the bike be started to prove it actually runs,
(2) Ask for evidence of proof that the machine is what it is claimed to be.
