B. Nickel is still making scopes at Marburg an der Lahn in west-central Germany. Since your scope is marked "Germany", rather than "West Germany", I would assume that it is a newer scope, made since the reunification in 1990.
They might still be making this scope, but you can look at their web site,
www.nickel-ag.com, or email any questions that you might have to info
jeg.de.
Awhile back, I was looking for an elevation cap for a 4x Supra and contact them, but since it is an older scope, they didn't have the part that I was looking for. One caution, I don't think that my B. Nickel Supra scopes are waterproof and it is possible that your scope isn't either.
