Just got this Ex-Military Valor. It has no Model number but I think it is a No55. It has a silent burner and still has its pan-ring. It works very well and is in very good condition. The markings on the bottom of the tank are "Cat. No4906" the "military crows foot or broad arrow", and date "1951". It also has the marking "3D" on the bottom. It has three decals that are partly still legible; one is warning to use only clean paraffin (Kerosene), the next is warning about not attempting to light the stove too soon, and the third is the lighting instructions. I would like to know if it is a No55? and does anyone have one with the full decals in completely readable state?. Also does anyone know what the "3D" means? Steve.
