Translations:GBD/7/en
Early GBDs were made only in one single grade concerning the wood’s quality, later supplemented by a second one, and there was only a very limited number of finishes. But toward the end of the 19th century, the demand changed. For example the Britons preferred darker stainings. More differentiated customer’s wishes made the introduction of additional markings necessary. GBD Xtra and GBD Special were very early models who’s names indicated special final treatments and / or fitments. The standard quality was stamped simply with GBD.
