Vintage Coleman Model 524 WWII Military Stove Surgical medical rare. This appears to be complete and reay to use! It keeps compression when pumped up but i’m not sure how to adjust the knobs on the front. They are stuck in place and i’m afraid top force them so a little research on how to get them to spin might be needed. It shows signs of age and use such as nicks, dings, scratches, scuffs and rust. It’s ready to restore or could just be cleaned up and left as it is of course. Thanks for looking and feel free to ask any questions!
