Very cool Eric !! I'll take as many Ken-Rads as I can find !

They are indeed nice to find, but I've decided to cut back. I'm not collecting anything over 400W any more, and selling off all lamps 700W and up.

I'm getting in the same boat ! I only consider buying if it's something special . I just passed on some uncommon incandescents as I already have over 1/2 dozen of them !

You just need a bigger boat! Very Happy

Nice find! I've cut back on my collecting too. Running out of space and it's getting too expensive to have lamps shipped in and the Restores have pretty much run dry.

I've stopped acquiring 400w+ lamps so far and only buy the lower wattages if it's special.

Same here, it's been a long while since I last added a lamp to my collection. Honestly, I'm perfectly happy with what I have now, so I don't need any more lamps. I'm focusing on building up knowledge these days, and I have even started a long process of culling the collection - I'll keep what is of highest historical and sentimental value only.

I'm slowing down simply due to not getting any younger! I can't take it with me...maybe I could if I was an Egyptian Pharaoh! Laughing
