Although my B50T rear shocks show no identification whatsoever, they seem to my eye be OEM and thus Girling. I was quite able to take 'em apart -- the top of the shock unscrews, revealing somewhat conventional guts. The inner cylinder on one of mine is corroded and the rod ain't in the best of shape, tho' hard chroming would fix all wrong with the latter. QUESTION: Is there any service out there that can rebuild these shocks, and if not, are any parts available for 'em? Oddl enough, the only seal that prevents the oil from escaping the shock in both of my shocks seems to be as supple as the day it was made. Any information much appreciated.
I've got 2 pairs of rebuildable Girlings. One came on my Gold Star Spitfire and the other pair was purchased from an old racer in Colorado.
If you can screw off the top go ahead and rebuild them yourself. Be careful to note the assembly sequence when you open them up and measure the amount of fluid to give you an idea of refill amount.
Don't get any of that fluid on ya.. open and slide apart real slowly while holding upright!

Thanks, Don, they were fairly easy to take apart (by unscrewing the top with a bicycle bottom bracket tool) and with the aid of a digital camera movie, easy to note the reassembly sequence. I have two issues, really: while the shaft seals seem in workable condition, one of the shafts clearly needs to be rechromed. That's easy enough, but w/o a source for new shaft seals, it might not be money well spent. Second, the cylinder (I'm making up terms as I go along) that is, the actual tube into which the piston with a ring fits, is deteriorated beyond a fix. Trouble is, Girling repo's possessing some authenticity -- at least from the eBay pictures -- are available at ~$150 USD, so practicality is a consideration.
Y'all know of any sources for the seals or for the tube?
BTW, your notation of measuring the fluid amount for refilling purposes reminds me of an old Fabulous Furry Freak Brothers cartoon. The brothers are at the table finishing up a fine turkey dinner. One of the brothers asks what the turkey was stuffed with. The brother who cooked the turkey announced that the turkey didn't need stuffing because it wasn't empty.
My situation is an analog: one of the shocks was as dry as the Sahara and the other had a light residue of oil.
Hagon do a series of Girling replacements which are technically better (double acting) and will have one to fit yours at a reasonable price. I wouldn't even THINK of restoring a rusty shock, not worth the time and money. Google them!

They are probably 50's Armstrong shocks. Identifiable by the triangular cam stop on the adjuster compared to the rounded rectangle of the Girlings. I may be corrected here, but I assumed Armstrongs were used until about 1957. Trev.
