Hotaling Portland T-55

Here is a glop top fifth that does not seem to get a lot of attention. Thomas indicated that these were distributed between 1875-80 which seems a tad early to me. I believe it was made about the same time as the Portland Hotaling amber coffin style flasks and date to the mid 1880s. I have seen these in light yellow amber to dark chocolate and every shade in between, with the dark chocolate example exhibiting millions of champagne bubbles and heavy whittle effect. The remainder seem pretty neatly made even though they are not air vented. To my knowledge, this fifth has been found from Alaska, to Southern Oregon with the latest find coming from Portland. These are open face whiskies with the ever important "Sole Agents" and of course the Hotaling name. I am not certain if these predate the Portland "Rick Rack" fifth or are from the same time period. The T-55 only comes with an applied top and are pretty scarce. Thomas indicates only 2-4 known examples, but I know of 9 of these in collections. Oregon just does not have very many glop whiskeys, and none are common. Have any of these been dug in California?
