So that's all the CRTs done. The unboxed Mazda was actually lurking in this box, which somebody may also like to save (radio not included).

One CRM121A box was marked with £18.3s.2d. Would that have been the price, or just someone's random jottings on a a box that was close to hand?
Mark, I can certainly keep the remains of the Cossor and hand them over for inspection at NVCF, I won't want to be taking them home again! I know that you're also interested in one, maybe more of the Mazdas.
I'm not sure now if I can make any headway with further testing before NVCF. TV isn't my speciality.
Probably time to decide on a price and start an Offered post soon.
