Hi I'm pretty new to the board but i thought this might catch your interest. While tearing out the back porch on my dads old house yesterday, i found these under 6in or so of dirt and leaves. I had forgotten all about them, having not see then since my dad died I assumed they had been stolen along with a few other "missing items". The one on the left was my dads Coleman 425(no letter) camp stove he bought it new in 1949ish. After sitting in my aunts garage for 25yrs, then in my dads garden shed for 10 yrs and finally outside under a pile of leaves and yard rackings for the last 5yrs. I decided to see if it was junk before trashing it. After putting a little oil on the leather seals and rinsing the tank out with some white gas it was ready to go. I filled the tank pressured it up and was able to have both burners running great in no time . It really is a testiment to the durabilty of these little stoves 40years of poor storage and abuse and it fires right off with even blue flames . The one on the right is a 425c that my dad got from one of our neighbors 10 yrs or so ago, it has received similar "care" as the 425 but has the tube on the fuel tank broken off in the control valve. The 425c also works great if it has the 425 tank on it, Im thinking it'll be getting a propane adapter, unless someone has a lead on a control valve assembly. Both will be getting rust repair and new paint over the next few days.
