WTB: tritium sphere

I have been looking high and low for a tritium sphere. They are used for some batteryless map readers etc. I need one for an artistic project I am doing. At this point size and colour are whatever I can get in time, but my preference is for green and as large as possible. Failing that, a half sphere or disc could work, but isn’t the best option.

Does anyone know of someone with one for sale?

I already contacted everyone. So far, No luck unless you find a used one. But, they have a shelf life. So thats a bummer too.
