Just wondering if someone could tell me the correct size for a solo saddle for the1954 Golden  Flash  and part number ?
Thanks

Not sure, but try:
42-9032
29-9335
6200-46

I think there are 2 sizes, a C series (smaller) and an A,B,M.  My parts lists are rather confusing, I think the key is the spacing of the tapped holes on the frame for the springs.  I take it yours is a plunger?  It looks like BSA don't give it a part number because its a bought in part so they list every nut bolt and washer except the seat.  I know this doesn't answer your question but I'm thinking google images searches on the part numbers may throw up something useful.  The alternative is to get the list of Lycett saddles from the 50s and work back.  I'm assuming its Lycette but could be Terry??

Do what everyone else has done, buy a generic saddle and modify the rear spring hole spacing or the length of the front mountings if need be.
The chances of even finding a "correct" BSA saddle (if that even existed back then) are remote.

   One critical dimension for Plunger Seats is that the two seat spring mounts match the frame mountings. Back then with limited choice I measured the frame, found a seat frame to match, powder coated, re sprung, new cover etc.  Came to fit it......too wide.  The mistake I had made was to measure the bare frame. With the rear wheel in place the frame was just that bit narrower. So I have one spring vertical, one leans a bit. With that bit of wear on the seat front frame pivot, sometimes it feels as if the seat is alive with a mind of its own. You'll also damage that nicely finished rear mudguard when the seat frame rear rail smacks down onto it at the first pot hole......

Hi, My '54 parts list shows it's part number as 67-9054  - may or may not be of help!  There are plenty of people offering new single saddles - someone there must surely know which one suits a plunger Beeza A10?   Search 'solo seat saddle'  on ebay?

When I restored my Plungie I bought a modern replica of the old style saddle. After about half an hour riding I found the saddle to be horribly uncomfortable. The metal frame and springs stuck into my bottom. I tried improving the comfort by putting leather between the springs and the seat covering but it made little difference. I felt that factors were; my weight is usually about 13 stone. The riding position, for me, was sitting upright with legs bent meaning all my weight was on the saddle; my legs and handlebars were not supporting my weight. On my modern BSA my legs and the bars take some of my weight.

I found a website selling custom bike parts. I bought a saddle from them with good quality foam. The modern saddle did not look Concourse but it was quite comfy.

G'day Adtrac.
About 40 years ago I got one very similar to this https://tinyurl.com/3z4xf74a
With 3 holes either side It fitted great. I also had GB's problem with the back rail on my bum so added a bit more foam.
Cheers
