The 8874s are bad enough and they are still made.

It should be possible to take parts from the 8873 and combined with a 
GI-7B (and some machining skills) remembering that dust from Beryllium 
dioxide is poisonous, to adapt the tube to work.  This would not be a 
job for a beginner of the mechanically challenged. <:-))  Having a lathe 
and milling machine would be a help too, so we've narrowed the number of 
people who could do this substantially to a very small number.

I've seen some nice 8874 conversions, but that too is not practical for 
most individuals.

73
