A good friend of mine has just acquired not one but two David Brown 1690 turbo models, circa January 1983-December 1983.
For the purposes of putting together a news story for Classic Tractor magazine, we are curious to know how many 1690 turbo models were produced during 1983?
A figure as low as 100-120 has been suggested, but we really don't know for sure. It would be interesting to find out.
