It's probably been done before but as I have access to the original Triumph Experimental build lists I thought I would list the 2000s and 2.5s included in that register.
Most, but not all experimental Triumphs have a 'X' prefix to their chassis number. The earliest cars in the register start in the X400 range and date to the late 1940s. The numbers progress in a numerical sequence (funnily enough!) through to the X900s in the early 1980s.
Prototype 2000s were code named as Barb (MKI), and Innsbruck (MKII) prior to officially being named as 2000, or 2.5. In the lists they appear initially as Barb/Innsbruck, and later as 2000/2.5.
So first I'll simply list the bare bones of the information from the register, and later I'll fill in any later information, or pictures that exist.

Work in Progress, please bear with me..........
Here is a taster courtesy of Ray Cole and taken by his Father Aub Cole on route to Le Mans 1965.
The Powder Blue 2000 in the backgroud with Ray Henderson leaning on it is X720 (5384 KV). John Lyoyd and Ray were towing ADU 1B on a trailer.
ADU 3B (in the foreground) is being towed by R Jones (leaning on 3B), and Bill Bradley behind 6105 KV.
Exert taken from Transport Arrangements for 65 Le Mans (courtesy Bill Bradley).
6105 KV was delivered to the Michelotti studios in Italy where it underwent a dramatic transformation into the first Stag prototype.
Aub Cole, and Pete Clarke were driving X713 (9081 VC), towing Spitfire ADU 4B. 9081 VC is quite a famous car appearing in quite a lot of factory publicity pictures.
Here is a picture of X845 (OVC 311M) driving through Nuneaton town centre early in 1974. Allthough all the shop buildings in the background are still there they have changed hands a few times since the 70's. It would be difficult to re-create this scene now as the town was pedestrianised some years ago.
Work in progress please bear with me......................
