Hi all, quick shot of the two barrel fin set outs. I believe the stepped fin was 63 only, but I've just put a set on my 62 rgs, I figure it's my bike so what the hell.

 So are you saying the difference is a cutout in the top fin for the finned header-pipe clam, and that's all   *????*
 
 Ah no, just had another look, and every second fin is differently cast

Well you live and learn!
I was putting the wheel on my SR today and although hard to see in the shed, for some reason checked the barrel and low and behold its got the staggered fins and I'd never noticed. Now the motor its fitted to is a 61, but I'm sure I swapped it off my american sourced 55 road rocket motor fitted in my sidecar... so I'm confused. Neither are RGS  or that late.
So it does make me wonder if they were available earlier or for other models

Quite feasible, but does this mean my SR is now an RGS replica   *conf2*

I would never have noticed, or thought to even look without this post, so now I have another piece of BSA trivia in my brain  *problem*

That thought had crossed my mind, much like the transitional large journal cranks that were fitted before the well documented large journal cranks from '58.
Or the differing alloy head castings.
Interesting whatever the story that there are differing thick flange barrels albeit only in detail.
