Fascinating ! My Late Dad owned an apple green 1933 20/25 FG 8484, I’ve been looking for it for years now.
Hi SS427 Camaro - according to the 20/25 "bible" "The Rolls-Royce 20/25 HP" - 3rd edition by Tom C. Clark, the car you refer to is:Chassis No. GMU23, Engine No. R5S, off test 22.08.32, body by H.J. Mulliner, 4 door 4 light saloon, body number 3991, first owner D.H.W Ritchie, was displayed at the 1932 Olympia Show - photos of the car appear in edition 1 (page 228) and edition 2 (page 93) of Tom C. Clark's book, as well as the Silver Jubillee sounvenir guide by Colin Hughes in 1977.
The last recorded mention of it was 1977.....
Have you tried contacting the RREC - to see if they have it in their records?
Have you got any images of it? I love a "lost" car!

Hello all,
A further update on the springs and dampers side - I have finally got the rear dampers into some sort of shape.
1) When I got the rear dampers apart, I found some "interesting" things. Firstly, both rear damper High Pressure valves were drilled as F81662 but then had solder applied -> one had one bleed hole blocked (to give F56916 spec), one had both holes blocked! The reasons for this are unclear - perhaps this was done as a temporary fix at the factory to update the valve specification. It seems unlikely that a previous owner would have meddled at such a detailed level. The fact that one valve had both bleed holes blocked completely shows that even at Derby, perhaps not everything went to plan! It is certainly clear from the West Wittering files that there were many many iterations of valves, springs etc in use and even some confusion over what was fitted when and where.
I have sorted this by getting a local jeweller to drill out the offending solder to give a single 0.03125” hole and hence make the valve into F56916 spec.
2) The spacers between the valve caps are critical to the degree of pre-load applied to each valve - and hence the pressure at which the valve lifts and vents. For the rear dampers, I think my car should have for the High Pressure valve F79927 - Joint Washer (0.050") and for the Low Pressure valve F79929 - Joint Washer (0.100"). My 0.050" spacers were quite corroded and missing entirely on one side, so I have had made 4 off 0.050" aluminium shims by Nylon Fasteners Ltd, Basingstoke - see below. An excellent service.
Once all back together, I'll have the satisfaction of knowing that another part of the car is now correct! All good small steps forwards.
Take care,
Andy
