Nice finds! MH cobraheads are pretty rare.

 Nice !!

Also found today...a Westinghouse Lifeguard H39-22KB, with a small font etch!

 I get it !!  I've reached the point where I will pretty much pass on most unless they're either something special or something I want but don't yet have . 

Nice, but I already have the full set. I hope someone here grabs them, though.

Another day, another cobra-head... 
(I need to stop spending, but when a bucket list item comes along...)

Just wondering if anyone is interested in a complete set of the GE Dichros 150 watt. I know someone who is looking to get rid of his set and I already have them all. The set includes all colors (blue, yellow, red, green and amber) all in original packaging. Otherwise they're headed for the dumpster since I have no place for any more! Free to good home just cover shipping.

Yep! And they also will run the Philips Allstart CDM145/U/O/4K, which are excellent lamps IMHO.

 Nice ! Plus you can also run MV which makes it even nicer !

A NOS Cooper M57 OVZ made over 20 years ago...I only bought it because its MH.
