Picked up a cute little piece the other day, I just need help with the marks, the dealer had it down as Dittrich and Silberfeld, but the only name present is Dittrich on the piece and Chile. Googling also only shows both names together, so is this the same Dittrich, if so, was this pre or post Silberfeld?

Thank you for any help in advance.
