Newly Acquired Stove

This new to me stove has British Made embossed but no engraving on the font, no discernable markings on the tin which leads to the question: which model is it?

I think it may be a Cobra.

 

Cobra 1/2 pint stove made by Samuel Heath and Sons.

Cobra half pint

George, do you have an educated guess at a manufactured date?
