Hey ppk guy, I've got one of these PPKs if you have any questions you'd like to ask.
I bought mine new back in about 1980. It was 49 Aussie dollars at the time, if i remember right.
All heavy weight alloy, with the Eagle and swastika make it a very attractive model to have.
I could tell you what they would be worth here, but it would be of no use to you there in Canada.
All I can say is, if it suits you, and it's at the right price, then go for it!
Dan.
