I agree that the mica stoves like this must be so impresive to look at while sipping your coffee in the morning. It does appear that someone did some work on this stove for sure, every mica bracket has new screws, etc. and it even apears to be new gasket of some sort up near the tops. The gap between the rear of that firepot and the grate is enourmous though (nut coal would fall through that Jesus in a velvet suit). The hinge pins are clearly not original (stacked hex nuts ).
I do feel if this stove where refurbished like new in an antique stove shop it would sell in a HOT second for at least $3,000k! (just my opinion), Even though I would try to explain all this and offer $900 and await his offer back of $1k cash... I'd grab it at the $1200 because I sure dont see alot of these 3/4 sided Mica "baseburners" w/ Magazine at any price.
