Antique high quality Vintage Christmas Lights

Antique set of What may be Disney Lights - these are very old and in wonderful condition. Pluto and the figure on the end in photo 2 do not light up. The others still do. Remarkable considering how old these are. I have never seen lights like these before so I believe they are quite rare and hard to find.
If you elected to place them on a tree and light them I would caution you not to leave them unattended as they can get very hot.
Not sure if they can be rewired but displaying them even in a bowl or shelf high quality is also an option. They are so unusual. I think that is Jiminy Cricket next to Pluto. Made of Glass.
