You're welcome!
It's not uncommon for Ferrets and other British Army vehicles to have spent YEARS in storage, so it could have been at Ludgershall for the whole time, but.......the cards are not always accurate (my Land Rover Lightweight definitely went to the Gulf in 1991, but there's not mention of this in any vehicle records!).
The manually competed Vehicle History Cards seem to have been replaced by the Merlin computer system in the mid 80s so there may possibly some Merlin history for your Ferret covering the Gulf War period. To obtain this, you need to submit a Freedom of Information Act request to the MOD Chief Information Officer - CIO-FIO@mod.uk - tell them what information you're after (Merlin record for your Ferret 01 CC 99) and why (private historical research).
Please let us know how you get on!
