I used to see quite a few of these trundling around the northern German training grounds back in the seventies and they were impresive. They had a good turn of speed and seemed to be very reliable. They also always looked smart, with what appeared to be a coat of high quality satin dark grey paint.
The Leopard 1 kit was a favourite of mine, I originally built one shortly after its original release which I think was in 1971. I built another one which I obtained from e-bay last year. I was hoping to post pictures for the first time but can't get the hang of it. Can someone point me to the part of the forum that gives info?
