On offer here is this BIG antique cathode ray tube / X-ray tube. 45cm tall x 18cm x 19cm. There is a wonderful website called the cathode ray tube site (CRTSite dot com) which gave me this information which can also tell you all about this piece. (If you like this sort of thing I would recommend having a look at the site it is very interesting and informative). On this website it told me this is an X-ray tube demonstration tube for gaede pump use.
I have been lucky recently to make a new contact in the Czech Republic who clears schools and colleges both in Czechoslovakia and east Germany and he has found recently this wonderful collection of old x-ray and cathode ray experiments this fantastic example was with them. It consists of a large round shape glass tube with nickel electric attachments at the ends and on the stem of the glass, Displayed on a turned wooden base, I think the base is later than the tube. Whether you intend to electrify it or not it is a very decorative item with a sculptural quality. The experiment is to introduce an electrical current which charges Ion gas particles inside the vacuum.
This is of course the forerunner to the cathode rays tubes used in old televisions. All of this can be explained on the website mentioned above. These old TUBES are collectable and can command high prices by collectors, I've picked this up quite a reasonable price so I'm not being greedy....
