I saw one of these recently at a gun show here in Sydney...brand new unfired condition. Was thinking about buying but bought an unfired K 14.According to "the book"circa 1983 and approx 13000 traded in towards purchase of new guns buy Hong kong police,many found as new in box and many well worn,many purchased by Acusport Ohio for resale on the used gun market.
Hope this helps or answers youre question.

Cheers AC
