Hello out there! This is a nice model from Optimus. No. 181 of the nickel version. The kitchen is never lit. The burner is oiled to not be damaged. Probably late 1940's or early 50's. Love the kitchen design! Last picture = nice combination Johan Lundström, Sweden
It's a beauty with that finish & looks good with the lamp. The tube for priming from the side of the frame down to the spirit-cup is a useful feature.
