Well I love building scale model planes and am always searching for something cool.
Today I got lucky.
I was in Antwerp and I went by a shop of which I have been a regular customer for a few years now and I spotted some very old looking boxes.
When I inquired about them, the shopkeeper told me that they came from the collection of a guy who very recently passed away and his widow decided to sell them.
I bought three: an early seventies Revell Grumman Wildcat, a late seventies Revell Hawker Typhoon (Still in shrink wrap, amazing) both in scale 1;32 and a mid eighties Matchbox Heinkel He-70 in scale 1:72.

I don't know if there's such a thing as "Vintage" model planes but I got some and already started work on the oldest.
