I emailed Feinwerkbau to see when my recently acquired Feinwerkbau 65 was manufactured. They responded the next day: impressive!

"Dear Mr. Kitchen,

Thank you for your email dated June 30th, 2016.

Please note that the year of manufacture of your air pistol model 65 with the serial number 104001 is 1979.

Unfortunately we do not have the information regarding the serial number of the first long tang 65.

Mit freundlichen Grüßen l kind regards

My pistol came in the box it was shipped in. Here are the pics:

The gun was postmarked 1/2/79. Got the feeling it's a 1978!

Actually praise to the company for getting back to me so quickly even if the info may be a couple of months off.
