[BC] bta-250m

[DANA PUOPOLO]

If I recall the blower simply bolts on by its spout. It should be easy to get
something from Grainger and adapt it to the transmitter. Just make sure that
the voltage is correct (I don't recall if those blowers run on 110 or 220 v).

I've seen many 833A's, 807's and others do fine after sitting idle 
indefinitely. My experience with 4-400's is limited. I may have a chance 
to restore a 20-V2 to working order but the blower for two of its 
4-400's is missing. Any suggestions for a replacement?
