The Great British Valve Project has produced real valves, namely new production units of the R-type from 1916. See

It is exciting that new tubes are being made, hopefully they will be able to expand their offerings once they get good at making them consistently. I assume this particular tube was chosen because of its relative simplicity. It’s nice that they have been able to reproduce technology from the 1920s, hopefully the can move through the decades and give us something from the 30s through 50s.
Makes me think of TECH TUBE - I have four of their 12ax7s that were based on cathode ray tube technology. They were made in the MULLARD Blackburn works. Looked like nothing I had ever seen before. The very opposite of this. They were trying something very different.
Sadly, it did not work out. The tubes had problems with microphonics - they came with a rubber sleeve that covered the tube - which could not help the longevity. Many reported glass failure - one of mine has a crack in the glass. I have not used them in years.

I still wonder why using original equipment matters. Using modern used lab equipment off ebay would almost certainly yield better results and should be quite a bit cheaper too.
Ediswan R-Type valve it's a very very interesting tube with tungsten filament, thanks to share Marcel.
