The purpose of RUM is not for me to say. It is a function of what those doing it want to do, and a framework of ideals. That has to face up to a need to respect private information and the law. RUM currently has little to chaff with against the latter problems. I think Barry's ideal might find more resistance. Trouble is like all really great collective ideals, there are always those who will pervert it to self advancement.
I have long been aware, like many collectors, that showing a car is to invite people to photograph and publish images of it, even worse, making statements about it, without reference to the owner. It has thus been many a collectors habit to restrict access, and knowledge, of that which they own, to retain control of the cars. I myself have suffered inconvenience and loss to people stealing identities, and cloning cars. This will be one reason certain vehicles will not be seen at rallies or events.
Yet buy the same token, not revealing a car can still lead to it being faked as it is assumed it does not exist and provides an assumed free original ID to be adopted. I have owned one very simple to prove original car that has a very convincing fake using its ID. If the two ever meet then someone is going to be very upset! In this case the group of cars were hidden for security reasons of remote storage.
As to the future and security of archive and register, be assured that there is a safe haven. I confirmed with David Hambleton that he remains willing to include part, or the entire, register into the Trojan Trust, or spin off a separate Trust, to administer, continue to build, and provide access and dissemination of the information in a way that is legal and fair. This as previously advised. The aim of the Trojan Archive Trust is gain museum space, or its own museum structure. It is almost entirely digitised with hard copies filed. I forget the number of documents, but its in the 1,000s. If that museum is achieved then the paper archive has a base from which it can be accessed by appointment at pretty short notice. With that safety net in place it is for the Register to find a better solution from a position of some strength, I think.
