Your PPK/s was made for Walther by Manurhin between 1969 and 1984. Smith and Wesson has no records of firearms produced prior to their present contractual agreement. They also will not furnish parts or any warranty service on previous made Walther's. Clydefrog. Smith and Wesson had several production agreements with Walther but they are two separate entities, no corporate connection with each other at all. S&W would have to triple its holdings before it could even think about purchasing Walther. Haven't you noticed, it is the foreign countries, that are buying American companies now.
