[CW] One of these is a Vibroplex jewel the other isn't

[D.J.J. Ring, Jr.]

Hi Walter,

The two bugs Deluxe and Standard are wired in today's versions - the 1948
to 1980 version of the Deluxe had an additional braid wire from the base of
the frame to the lever arm - it bypassed the non-conducting jeweled
bearings.

If one is Deluxe, it has a jeweled bearing and the cup is round and has a
reddish jewel at the base, the trunnion pin is shaped like an elbow to fit
it.
The Standard Vibroplex has sharp but rounded pins - you can see both here.

Note the reddish color in the 3rd picture.

My photography was going to show you what happens when the old
style adjustable top screw (as they originally had in 1948) is used and
someone tightens up on the screw - the jewel breaks.

I had a good photo of the remains of the reddish jewel but it just fell out
so all I had on my first message was the shape of the jeweled bearing
housing. Just the housing except for a hint of the red jewel in the center.
