Now I know that I'm going to cause a bit of controversy with this project as it could be construed as vandalism. I have bought an HMV 900 EMI MKI mirror-lid TV which, to my eye, is an ugly beast. I have also bought a Marconi 705 MKI mirror-lid cabinet with only the radio in it and the rest of the guts missing (CRT assembly, TRF, Sync and PSU chassis).
It is my plan to strip out the 900 of those chassis and fit them in the 705 to complete the set.
Now, Vandalism?? According the the Early TV Foundation database, there are 19 HMV 900 extant but only 7 Marconi 705s - I can't understand why that is as, in my opinion, the 705 is a much better looking, not like the monolithic 900!
All the records of what chassis etc. were installed in what sets have been lost (or more likely thrown away) in the passage of time.
So, what do you think, guys - pull no punches. I might ignore all that you say but I may not - if I can find the appropriate chassis, I will obviously not do it.
