There was one well known trader who happened to get hold of a few refurbished Brens a while ago and advertised them as if they had somehow come out of the factory gate and then got stuck in some kind of time capsule, packed in grease, for nearly 80 years. Being involved in collecting for some time I knew what questions to ask and it turned out that they were simply refurbished Brens that had come out of storage (then been de-activated). The price being asked for them was a fair price for what they were- refurbished Brens but why on earth it couldn't have been stated in the advert I don't know. I always find it best to ask questions by e-mail rather than by phone that way you normally get a written (e-mail) reply.
