This is a WOII Nederlandsche Arbeidsdienst (NAD) “Arbeidsdienstplicht” Service Citation + papergroup.
All on name of P.W. van Boxtel. The NAD citation is obviously the best piece of the froup and is a wartime item. The other items are also from va Boxtel, but from the Dutch army postwar. Het “zakboekje” is empty, but is mentioned in one of the letters. All is together belonging.
Priced very good, it would be nice to check and research it all.
