"Vacuum Tube" Tesla Coil - TOY

[fuzzytomcat]

Hi all,

He is a item some here maybe interested in, from a magazine "How To Build It"  (Jan, 1932)  titled article - Vacuum Tube Tesla Coil Does Fascinating Stunts. It seems like a harmless toy    ...... looks like something fun to build or make "BIGGER". 

Enjoy,
Fuzzy
