[Hallicrafters] Tropicallized or MFP

[rbethman]

Unless BC-610s were ship mounted, (None that I EVER heard of.), your 
interpretation would seem to be correct Rod.

All BC-610s and their associated components are ALL stamped MFP.  Then 
again, so were ALL R-390As.  I do NOT believe "maritime" had anything to 
do with it!
