Re: Baird T5 restoration project.
The 15MW4 CRT is a post-war replacement. Certain modifications were required to install the tube including an octagonal shaped wood adaptor block to move the position of the focus coil.
The pre-war tube was the Cathodevisor 15MW1 or 15MW2. A 15MW3 was made but this was a post-war tube which was similar to the Mazda CRM151.
