Hello, mark of Arthur Otto, active in Cologne, Germany since 1903. Moved to Lippstadt, Germany around 1980. Not a maker, but a retailer of new silver in antique styles, often produced in Italy. Regards, Bahner

Yes, the mark with AL is clearly an Italian mark from Alessandria.

Try to find out the number that is before AL and we'll know the manufacturer
