My Primus 210 does not have a stamp on the bottom of the tank indicating the year of manufacture thus leading me to believe that it was post 1964. The tank also does not indicate who the manufacturer is. Only a Primus logo and Primus 210 -Made in Sweden.
The stove also has a fold-up (square) mental wind deflector which fits over the burner and the stove fits in the usual tin case.
Can any member shed any further light on the subject?
