These two extinguishers were recently removed from a log cabin in northern Wisconsin. The cabin was built in 1957. The serial numbers (G600004 and G600100) on the extinguishers indicate a manufacture date around 1960-62. They may still hold a charge and may also still be pressurized. The extinguishers would make a great addition to a man cave or to a collector of all things fire related. They are in excellent condition and show very little paint degradation or wear.
