Jim, you might also try carbon dating. Ya might have an oldy there.

My R-390 None A, that I got last summer had a dried or petrified bug in the RF
deck It looks like what we call up here, north of the US border, a May Fly. It
looks like it got zapped in mid flight. The legs are retracted and both wings
are frozen in the down beat. Will encapsulate when the restoration is complete,
in about 3 months. If I had good digital camera I could share this with the you.

One more item and it's related to the Deoxit and the problem with over
application on rotary switches. I just about ruined a Yaesu FT901DM two years
ago by applying to much Deoxit on the Band switch. The switch just about froze
up. I sprayed it  heavily and often with isopropyl alcohol over a two week
period. This seemed to help. It is now just about normal. Time seems to help
also. My First R-390A was under restoration and suffered the same problem on one
of the front panel switches. Stopped in time before I caused to much damage.

I have tried all sorts of Deoxit applicators including Q-Tips, syringes, very
fine artist brushes etc. All of these were to large, unwieldy or to expensive.
Well this morning while taking the wife out to spend some of my hard earned
money, I dropped in at a local hobby shop specializing in model trains and
plastic model just to browse and kill time. What I found was something called a
Microbrush.  As soon as I saw it I knew that I had found the perfect Deoxit
applicator. Total plastic handle length is 4 inches. Diameter about 0.125 inch
with the last inch tapering down to 0.018 inch. At the tip is the brush which is
molded into the tapered plastic. It is about about 0.100 in long and 0.040 in
diameter. I tried it on the R-390 Harness switches and connectors. Much better
and easier to use than the expensive artist brushes I have used. For tube
sockets it's perfect. The brush will compress enough to fit  within the rotary
switch contacts. I used their Superfine size.

The MFR has an internet site that describes the product very well. The price is
right also, 10 for $1.75 CDN or about $1.10 US. Your local hobby store should
stock them. The North American Free Trade Agreement has opened up to us
Canadians a wealth of U.S. made hobby goods at fair prices. Prior to NAFTA we
bought U.S made goods. The duty made  prices out of reach on a lot of U.S. made
hobby supplies. The pacific was our only source of reasonably priced goods. This
is not a political statement but a statement of ordinary consumer satisfaction.
Will climb down from the the soap box and say good night and have a good
weekend.
