probably of no help? have you tried tom at continental shooting supplies he use to be the importer he might be able to help,
RUAG are the importers now I believe but I would email Susan Adam directly at Docter and ask very nicely she might send you one (s.adam@docter-germany.com) their customer service is second to none very good people to deal with unlike some she might pass you on to Harald Ros who takes care of servicing another good person to deal with.
