Have posted this on the UKRA open forum but for those that dont read
that or have access see below

A friend from Rolls Royce Heritage at Derby rang me last night to let
me know that they are having their yearly (ish) open day, where
members of the public can turn up and see the exhibits have a tour.

Rolls Royce Heritage at Derby - Open Day

Date Saturday 13/09/08 10.30 - 16.00
Historical collection and exhibits
The products include aero engines, cars, rocket engines and industrial
and marine engines. There is an extensive collection of these
products, lovingly restored and maintained by a group of enthusiasts
drawn mainly from retired ex-employees. The collection is currently in
large premises at the Light Alloy Foundry, Osmaston Road, Derby,

The collection includes such treasures as a 1904 Siddeley Autocar,
which completed the Brighton run in 2004, the last Armstrong Siddeley
car model, the Star Sapphire, WW1 Puma aero engine, sectioned Cheetah
radial, ASX turbojet of 1942, Python, Mamba & Double Mamba turboprops,
Sapphire and Viper turbojets, Stentor and Screamer rocket engines with
a sectioned Blue Steel nuclear stand-off bomb (cruise missile),
Maybach V-16 locomotive diesel, SM1-C (Spey) marine full size mock-up,
and many more.
The latest additions to the collection are a Black Knight Gamma Rocket
Engine and a Sapphire 346 Pick-up truck.
There is a good library, partly housed at the Coventry City Archive,
partly in Derby. The Branch has excellent workshop facilities for
restoring exhibits, and currently about 50 people enjoy working
sessions.
