Hi Herb and Ron....
My thanks for your comments. Maybe, since we have this thing called the "Internet" and "instant communications", it influences the way "research" is conducted.? I'm still an old fashioned guy, I guess - and do my own research on subjects that interest me. I frankly applaud any author who commits their time, research and efforts to permanent books - as they are out there for all to see - well, *forever*. Take Datig, Gibson, Still, Costanzo, et al. - and it's a pretty short list given the past century of collecting - and compared to the number of collectors (tens of thousands or more?). But those authors and researchers have "let it all hang out" - and have earned a special place in the collecting world by virtue of what they have personally accomplished.
OK - off my soapbox..... <img border="0" title="" alt="[Wink]" src="wink.gif" />
Doc - I believe you have a variation #3, as described above. Your comments would reinforce that, if I think you are referring to the photos in Gibson's book that I have in my mind (I'll check tonite when I get home).
For that, you would have one of the rarer types - of that later allotment that, as I recall, Mr. Gibson notes as "100". I think it may be slightly more then that 100 estimation, based on the observed serial numbers....
