HISTARCH,

I have a bottle base with the following base mark:

DUBUQUE MALTING CO.   DUBUQUE, IA.

The complete name for this company is the Dubuque Brewing and Malting
Company, whose company buildings in Dubuque were added to the National
Register of Historical Places in 1978. Register information online only
gives bracketing dates for the "period of significance" in 25-year blocks,
and for these buildings give 1875-1899 and 1900-1924. I have looked in the
familiar bottle base mark reference material which include liquor bottles
(e.g., Toulouse; Wilson & Wilson), but have found nothing regarding this
bottle or company.

Does anybody know more-exact dates for this bottle base mark or company?

Thanks,
