Dug this bottle in Texas this past weekend and can find nothing about it. Embossed on alternating panels around the neck "Diablo" then "Salsa" then "Diablo" and so forth. Very late tooled lip...I suspect this dates from 1910-1915. Looks to me like it must have been a Tabasco competitor of some kind...I understand that the Pioneer Pickle Factory in Sacramento started selling Bergman's Diablo Pepper Sauce around 1900 but I don't know if this is the same stuff. Anyone ever seen one of these?
