I was hoping some-one can tell me the correct BSA Part numbers for the upper and lower fork yokes fitted to the BSA ZB-31 models.
There seems to be a few different numbers claiming to be for these models, as well as Gold star, and even A series.
I have a copy of the Dragonfly Ecatalogue, but I cannot get the page to stay open for some reason.
I believe there is a part number for each cast on the underside in raised numerals.
Any help would be much appreciated.
Thanks in advance.

G'day Keith,
No problems with Draganfly's catalogue here.
They state top yoke 66-5088 for '49-'52.
bottom yoke 66-5089 for '49-'53.

Hello Matty; Many thanks for your help.
I have a copy saved on my tablet, and also flash drive, for when I am travelling around.
I can't get the page to stay open, it shuts off after a few seconds for some reason.
Your information will help me a lot, thanks again.
Cheers Keith

And these numbers will not be the same as the ones cast / forged into the parts.
Those numbers are for the bare casting/forging, prior to any machining.
Generally the finished ( parts book ) number will be one or two digits away from the raw number but for some thing like the top & bottom clamps they can up to 10 to 20 digits away as that caprt is used by a variety of models all with sightly different machining thus a different finished part number.

So that explains why the the confusion. Googling for info with out the benefit of the Dragonfly catalogue, I thought it is me old!!!!
Studying many eBay listings, people I'm sure try their best, but I can't find a pinpoint certain description. Any idea what the part cast numbers might actually be for the ZB-B31 ????? Should I add a couple of twenty's or subtract??? Or just buy in many, and hope I get the right one pot luck.
Thanks Keith
