I recently had a friend purchase a stove on my behalf which I received in the post today. The burner is a regulated type Primus, I’m guessing from the 1930,s? The tank is steel and has no visible markings. Pump rod, pump tube, and filler cap and even the pot supports are brass. The nicely rounded spirit cup is steel. The feet are also steel and I think an uncommon shape. The NRV has a hexagon shape so the usual Primus tool won’t work I think. Can’t get a good picture of that. Would anyone know what I have on my hands here? Many thanks. Tom
