[RFI] Stoddart equipment available

[mstangelo at comcast.net]

Ken,

I don't know what the market os for vintage equipment these days. Have you considered donating them to an Aircraft Museum. They may be interested in them. You may want to post this information on the Misurplus list.

Good Luck, 

Mike N2MS
