Hello, both marks were registered in 1889 for thr Frankfurt based company of Breidenstein & Renaud. The company seems to have existed until the 1920ies. There is no record of it after that. If there is an engraved date on this piece, it seems spossible that the engraving was done much later than the production. Best wishes, Bahner
