I went to the TRW swap meet on Saturday, and picked up a 866 mercury vapor
rectifier. The thing has a 2.5V 5 amp filament. Good thing I had this large
transformer in my stash with a 2.1V tap. Needed less than 50V to light it
up, and get the emission up to get more than 50mA thru. Tube is rated
Much UV leak out do you think?

You read my mind - I would have thought that this was a real (not
imaginary) danger. Nearly all UV is absorbed by the front of your eyes,
causing corneal damage, cataracts macular degeneration.
I'd

Ordinary glass (i.e. the tube envelope) is opaque to UV. That's why UV
lamps have to be made out of quartz.
Don't break it, though!

UV covers a large wavelength range - from about 400nm to 10nm. It seems
that anything shorter than 300nm is regarded as not good for human eyes
and that normal soda glass absorbs a lot of that, leaving mostly UVA (long
wavelength UV or NUV/near UV) as radiation external to the envelope -
Any kind of filter I can stick on this thing to block the UV ? Tinted
Acrylic ?

Fo a go-no go test you might look to see if the UV is strong enough to
illuminate anything with UV writing on it. UK currency notes and
European passports carry invisible (to the eye) markings that
