Jensen 24AJ is now known as the Ashley 24A. Mastercraft Metals, formerly Jensen Metal, sold it's furnace division to U.S. Stove Company about 1998. U.S. Stove continues to make the 1300, 1400,1500, 24A, and 30A, the most popular furnace in the line, but does not make the boilers or other furnaces (although many parts are the same across model lines).
The former 24A (Jensen Product) was followed by the 24A (US Stove) and sported a red paint job instead of the hammer tone gray or almond of the earlier versions.
U.S. Stove has held the line on pricing, so the 24A is still the most affordable wood / coal furnace US Stove COmpany offers! It's best at heating smaller to mid-size homes. The furnace uses forced draft (thermostatically operated) and uses a furnace control center (included) to operate the 2-speed distribution blower.
