[BC] bta-250m

[Stan Tacker]

Check the Grainger online catalog.  I replaced a 20-V3 blower with one of
their units.  Same physical size, a little more airflow.  Worked great.

Get that 20-V2 working and ship it to South America!

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?
