I'll give this until the weekend and then tot up all the sets. I think I'll also produce a table as suggested by Helder Crespo.
If you have anything you'd like to add in the meantime about your own TV12/22, such as serial numbers, feel free. I'll sort all the posts out at the weekend. TV32 and TV62 owners should also post.
Obviously, this survey will be limited in scope, since it only includes sets that people have posted about here.
From
THIS earlier survey, we learned there were about 700 405-line-capable sets still working in 2019. It will be interesting now to see how many are bakelite Bushes!
