Russian Hydrogen Thyratrons are a lot cheaper then that. And there is no way the original cost on that tube was 13k/ There is plenty of info on how they are made out there, if you have academic or military credentials to access it. Problem is, materials for a one off are not cheap. No one is going to want to slice, polish, and metalize just one piece of Alumina for you. The jigging and materials alone would burn up 5K$ at commercial prices. These are made using economies of scale. There are producers in China, India, USA, and Russia.
