Hi Ken,
I remember looking for the same thing when we were installing one of our
magnets. The adapters we had been using were also from long ago so I
didn't know where to look either. I was recommended this website and
it's been a great resource.

In the end, I can't remember if we chose the thin-wall or thick-wall
series. Nevertheless we had no problem securing our LHe transfer line to
the dewar with these and this is at least a start for where to find them.
I also remember being puzzled why they are called christmas tree
adapters until a technician showed me a set of various sizes all stacked
one within the other from large to small and yeah, then it kind of
looked like a christmas tree. Still, it was a really frustrating
description when I first started googling "christmas tree adapter".
Hope this helps.
Take care,
Paul
