Omps2 in Italy would be the first place to check, if you ask me. They have the widest range of Diana replacement parts, including stocks, that I know.Waffencenter Gotha and Versandhaus Schneider in Germany are the two other places I would look into. They both have replacement stocks for German springers, but the selection is ever-changing. ETA: Chambers in the UK also has gunstocks in their wide range of replacement parts. These four are the ones I've personally used many times for parts for my Dianas. There may be others, especially Stateside.
