That's what I was thinking, hoping, the mark dates it to the late 30s so about the right time for Murray ? 

[Paul S.]

yes, that could be about right for Murray.                  I've lost the plot Keith  -  I had the impression you finally said this was uranium, but now I'm not sure.

hmmnm  ………..   you sure that isn't a manganese glow Keith  -  looks a tad dull greenish to me.?

[chopin-liszt]

I think that's manganese too. A lot of it, but it's not bright enough for Uranium. There wouldn't be "bald-of-glow" areas.

The 'decanter' thingy does look a bit odd, here's a better one of the a glass 

[chopin-liszt]

That looks more U-ish than Mn-ish. 

How far away can you get your UV source from the glass, while the glow still shows?

[Lustrousstone]

It's uranium. You can see it on the edges in the daylight pix. I asked Keith on Facebook as soon as I saw them

[keith]

You have to get really close with the light source for a reaction 

[chopin-liszt]

It's smokey grey glass, not green. 
And if you don't get the reaction unless it is very close, we're back to Mn.
