[Milsurplus] Comment on "Shortwave Receivers Past & Present" Fourth Edition

[Hubert Miller]

So I bought the book, "Shortwave Receivers Past & Present :  Communications Receivers 1942 - 2013. 
The book is heavy, 6  lbs. , and worth the $50. If you're like me, you can flip to any page and enjoy a pleasant diversion.
But - "communications receivers" includes Ramsey kits, which had no frequency indicator at all, just an unmarked knob?
Or includes Minerva Tropic Master 'morale radio', or some bottom end Olson AC-DC with a couple shortwave bands ? 
Who communicated using those?
Also the title date seems to allow some tolerance. I see a few models with a given date of  1938-1939.
The book is a massive work. To me, it seems an impossible work; it tires me just thinking of the near-impossibility. 
So, much credit and thanks to the author, Fred Osterman.
But - I am a nitpicker. 
"Collectible" is only spelled one way. I found some omissions; I can think about a half dozen U.S. models. If you look at 
one of Fritz Trenkle's books, you see that opening the chest of German WW2 receivers means a lot more work. Or look
at the Yokohama Military Radio Museum website. None of those shows up here. For a future edition, the net needs to 
be cast wider; notices need to be placed, and people ( like me ) with rare models, motivated to submit photos and data.

No ARA, no BC-229, no RU. Navy RU was certainly a "shortwave communications receiver", if you're going to have a Minerva
Tropic Master in the list. The Northern Radio N-605 had no BFO. There seems to be an embarrassing conflation of Northern
Radio [ Seattle ] with the east coast Northern Radio. Who provided that info ?  Some  the comments are useless and purely
author's opinion: the Collins R-392 is "not a pretty radio". Thanks for that useful comment. Some common Lafayettes are
described as "scarce"; scarce I suppose, because they are no longer manufactured ? The "value" data, where provided, is 
useless; the market is very dynamic and an unsupported figure is unhelpful. The common equipment will continue at best
to slowly decline  in value, due to oversupply, while truly rare but also desirable equipment will continue to climb. 
I will contact the author with some corrections and additional model information.
