We are trying to find out about a Nathan Dohrmann Co., San Francisco.
We found a white-improved earthenware plate/bowl fragments with green
trademark -- 'VITRIFIED' beneath fragmented lion motif; 'JOHN MADDOCK
& SONS LTD','ENGLAND', 'PANAMA', 'NATHAN DOHRMANN CO', 'SAN
FRANCISCO'.
We have identified John Maddock & Sons, Staffordshire Potteries, ca.
1896+, but we have been unable to find anything on Nathan Dohrmann Co.
Thank you
