From the 1950s until the 1970s the German Air Force had an active 1/200 scale Identification model program. The aircraft covered most of those that could be encountered in the European Cold War Theatre.
I have been told that they were made by the Hansa company of Germany. The models were made either in metal or lightweight resin
The set had 4 numbered boxes, more like suitcases or crates with handles and was added to as new aircraft came on line. {Similar to other German Identification model programs underway during WW 2- the Wiking 1/200 and the larger 1/50 wooden Luftwaffe sets.}
Each box had two sides which opened independently with a key {again like the WW2 sets}. There was also a list of contents for each box.
Here is box No.2, Canadian and English, and some of its contents.
This model is numbered 2006 and has inscribed under the wing GR-1
I have the 4 sets plus an earlier set of the No.2 should anyone want to see them.
From time to time some of these models were sold on ebay as unfinished kits in an individual plastic bag.
