Vintage coleman instant-lite gas iron model 4a in "cool blue". These were made in 1929-1948, i believe this one to be made in the 1940s. They are also known as a sad iron, it's also self heating. The brass tank on the back was filled with gas, then open the top valve to release pressure, next light the pilot near the bottom with a match, then you can fine tune the flame by the handle on the back and your ready to go there is slight rusting in a couple places and also some worn off paint on the brass tank(see pictures)but still in very good condition. This item is made of metal and brass, wood handle.
