George,
Thanks for your condolences and thoughts.
The originals are almost A4 size and the only thing on the back are the references A16-3, 93-4, and A74-9 (same order as the displayed photographs). All I know is that when either Cannings had folded or was about to fold, there was some sort of management buy-out. At that time Roy, who had always very ably played the stockmarket, had 3,000 shares, but insufficient for him to become one of the six directors of the outfit, which carried on for a few years. Then a Sales Director, a salesman, Roy and one of the secretaries went to work for said Sales Director who had set up a new Company and it was basically working from little more than a lockup garage. They were merely supplying former Cannings customers with bought-in consumables and Roy was making a few specialised items for sale to these customers. They only ever saw the Sales Director when he came in to pay their wages weekly.
The salesman was, of course spending most of his time visiting customers, so it was basically just Roy & the secretary, First to leave was the salesman, who had reached retirement age. He was followed later by the secretary, and that left Roy to deal with everything, though he was an accomplished typist from his National Service days in the Army Pay Corps. Eventually, Roy, who had reached retirement age himself, had had enough and the Sales Director said he was putting this Company into liquidation, something he had threatened to do for several years. Roy stayed in Birmingham for a while and then left to be closer to his son in Hampshire.
The above paragraphs are a summary of what I gleaned from Roy on his various holiday visits to my late mother in Poole over the years, and I'm unable to name names simply because I don't think he ever mentioned anything other than forenames, and it was all quite a few years ago now. He'd spent his apprenticeship with an electrical contractor, mainly installing pumps at the bottom of deep shafts, and when that work wasn't available doing "house-bashing" as he called it, rewiring houses for this contractor. During his time at Cannings, he spent two and a half years in Roumania, in charge of the installation of the plating plants at the Lada factory.
