Now, Mike, you know very well that if it isn't just like the one in the book it simply must be a fake

Ha ha!
Actually, Conogre and I are on the same page here; I can't tell you how many collectors and dealers I've encountered who say "I don't know what this is; I've never seen anything like it" as an expression of disinterest, while I say it with wonder.
One guy told me that about a Collins 1005 while he had 3 others under his counter about 7 feet away for $140 each

"I don't know what this is...." was his excuse to try to get it off me cheaty-cheap.
