I'm replying to my own post to let you know the reflector
stripped the picture of the Delta out of my original post.
It too is available in a direct email.

Hi guys,
Sorry about the poor quality. I scanned this into "Word" format
so that I could paste it here on the email.
If anyone is interested in a "clean" PDF file of this, let me
know and I'll send it to you. The file is big, though. It's
about 380 KB.
Remember, back then vendors typically specified "Input Power",
not "Output Power". So when they said 200w, they were talking
100w by today's standards.
This baby "looks" similar to the old Argosey II. 73 - Rick
