Vintage 4 colour wheel light for aluminum christmas trees.  

No manufacturer sticker, but it does appear to match up with the older Penetray models.  

There is a fair bit of age wear on this lamp.  The blue portion has a missing portion along where it sits against the red wheel.  The plastic is old and likely quite brittle - I would strongly suggest not trying to disassemble the colour wheel.  

That said, it runs well, and lights up as you would expect any lamp to do.  

I will remove the colour wheels and pack it between 2 pieces of cardboard for shipping, which should keep it safe.
