Going to go look at an 04 55-shp22 to put in dads shop. Mfg 05/2004. I understand the sh stoves were sold by lowes. Anybody know what the "e" means? It has the same control panel as my 2016 and pics show same burn pot, wear plate, and baffle. Needs a lower auger motor and igniter but price is right. Thx, Bubba
