From another section of the parts list. Hope this is of some use.

There are a few different part numbers in mu BSA Parts Llist (for 1949 - 1952 B31's, Gold Stars and others). I attach the information - but find it hard to be sure which tank is used on which bike - rigid, plunger or Gold Star.

Looks like a bit of a bodge up - I will fit something more reliable

On my 1952 model the saddle measures 13.5" from back to front, the support springs are on 8.75" centres and the front mounting bolt centre line is 11.5" from a line connecting the support springs. It fits in the tank cut out. The front crossbolt is, however, attached to the saddle metalwork using two extension plates, one fitting on either side of the frame mounted boss just behind the tank. I am trying to work out how to attach a picture.

Nice looking bike - and other interesting bits reflected in the tank?

On my '52 plunger model it is 19.75" from the centre of the hole in the clevis end, to the end of the rod at the drum end.

Hello  there.
This is my  1952 B31 which has been living in my garage virtually untouched for 12 months. I've just recently got it running, but a few jobs to do. You might notice front wheel is well off centre - nearly touching right hand fork. Looks like it's not charging very well, but basically it seems a sound bike which I want ready for cake shop adventures around the Lake District next Spring.

Been away for a couple of weeks. Thanks to all for replies. I think I'll start with a generic stand and see how it goes.

Thanks to both of you. Unfortunately the part on ebay won't fit as my bike doesn't have the welded lug to which it bolts - as on Greybeard's bike. I may buy a clamp-on universal stand to help with moving around the garage and look at some way of preventing it rotating around the frame tube. Looking at the ventele device makes me wonder if something down from the seat stay (bicycle parlance) could be used to do this.
Some sort of lever added to the centre stand is also possible I suppose.
Thanks again.

Hello - this is my first post. I have a 1952 B31 which I am currently making roadworthy. I will be putting it on the road to use regularly -  mainly to visit cafes and cake shops around the Lake District. One of my major problems is the lack of a useable stand so that I can work on the bike. It's currently leaning against the wall, which isn't convenient.  The bike has a centre stand but this offers no leverage at all and I find myself having to lift the weight of the bike to get it up on the stand. This is too much for my 69 year old back! Despite searching around I can't find a side stand to fit the plunger frame. Can anyone advise on side stand, source of better centre stand, mod's ?
Thank you.
