This one took some serious research, lots of bits and pieces from several different sources. What we have is a fire brigade truck produced about 1970 by the Swiss firm Geser. Geser products were specialized vehicles manufactured on various chassis. including Ford and International. In this particular instance we have a: Geser T60 4X4, using a 120 HP Jeep Tornado gas engine. I'm not sure if the whole chassis is Jeep, or not, as the vehicle seems a bit large for any Jeep chassis that I am familiar with.
