[Boatanchors] National Select-O-ject versions

Sat Sep 13 22:36:53 EDT 2014

Carl Huether will probably chime in on this but I believe I have read that the SOJ used a chassis and case from the SAF which was an attempt at a UHF converter to feed a VHF TV receiver.  

I may be all wet on this; it's just in the back porch of my memory.
