[Boatanchors] Allen D. Cardwell Receiver

[Carl]

And its been downhill since 1964, what a shame.  Buy the competition and 
kill almost everything. Alan D must be turning over in his grave. You might 
say Cardwell single handedly killed the majority of the variable capacitor 
business in this country, including their own products.
