Be careful on this one. I don't have proof, but I wonder if the seller is possibly Joe Dorgan?
The eBay seller (yardleydog):
-lives in Tucson (where Dorgan's shop & house are),
-has 6
FS-Model 17 type beacons for sale (what are chances someone in Tucson has 6 beacons besides Dorgan),
-took pictures showing no visible background,
-the workbench the pics were taken on have a few oil spots--John Dorgan was pictured sitting at his oil-stained workbench in his final years,
-one picture is taken outside on a brick walkway--the same type of walkway that is behind John's house,
-the seller says 'these lights were in storage for several years in a shed'. Those who knew John knew he had a shed garage behind his house full of spare lights & boxes.
I'm not saying it's him, but I think there's enough reasonable suspicion to use caution. I've been watching all six lights, but am not bidding due to my belief it could be Dorgan.
Here's some pics to back up my claims, including one picture (reflection) of the seller. Pay attention to the reflections in the beacon skirts, of the person who took the photo, the shop where the photos were taken, & the brick walkway. Note the brick walkway in the google earth view of the late John's known address on Stella Street in Tucson.
