Any plunger set up from any B31/33, M20/21 or A7/10 will fit. Shouldnt be too hard to find at a swap depending where you live.

By your e-mail address I am guessing you are in the UK. I would think you would have to go to a few swaps and see what you can find. Maybe the UK members could suggest some places to try.

Bill, I got a set for my A7 about a year ago off ebay for a very reasonable price.  This was in the US where plunger bits tend to be rarer.  You should not have much trouble in the UK.  If you come up short one left side slider, let me know as I've got an extra NOS one.  I bought it thinking I would piece one together from bits and then found a complete one.

Bill,
I've got a set of black painted spring covers as well as the centre columns and the bits for the axle (Spindle clamp lug) to go through, and much of the rest. The crome covers need recromeing, and the springs are shot, but there's a few other odds and ends.
The spring covers have recently been profesionally repainted black, as well as the axle lugs.
I'll need to dig the rest of the stuff out to see what condition they're in if your interested.
I replaced my old ones with a lucky e-bay purchase,
John

no probs - let us know wha you need and I'll see if I've got it in my box of leftovers.
I'll also give you, and the rest of the forum, the method of how I got the plungers back inot the frame. Contrary to the BSA workshop sheets - I couldn't squeeze the springs by hand - they must have eaten alot of porridge back then!
