On offer here is this antique cathode ray tube Glowlight oscillograph tube. Glowlight oscillograph tube Max Kohl. The first kind of oscillograph, it worked with a rotating mirror system after Gehreke-Ruhmer. 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 a cathode ray tube. 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. All of this can be explained on the website mentioned above.
