The tube is a RFT B7 S4-01
It‘s from an EO174A Oscilloscope. Nice green and pretty good to focus and linearity to the edges. The tube and first version of PCB could be viewed at https://m.youtube.com/watch?v=zTyXJE2faXw <https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fm.youtube.com%2Fwatch%3Fv%3DzTyXJE2faXw&data=05%7C01%7Cjoerg.postert%40otto.de%7C934c425d99ee4b01af7008db202467fd%7C8794e153c3bd44798bea61aeaf167d5a%7C0%7C0%7C638139112953496744%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=7yQJJjU6SCFcfQu%2BVxKoA8R9%2B%2FrsA1AVJOuO76nxNq8%3D&reserved=0> I do not plan a kit or selling like david forbes do. First of all, it is initially his design and software. Second, I do not have the will and time to go through all the regulations EU/Germany has for selling such electronics. I could share the PCB if I order the next batch, but it is not finished, yet. I plan to add ESP32 for NTP and web config.
