[R-390] The rare bears

[Cecil Acuff]

Well there was also the one that was built for a retiring official from 
Collins if I remember correctly...placarded as such as well...  If I 
remember correctly it showed up in recent years.  I think in a ER issue as I 
remember.

How about the rumored Electronic Digital Readout models....

The few that had prefessionally installed product detectors.

And maybe the civilian Rocketship EAC models...

Just a thought....:-)
