No expert on these stoves here , but it does have 'condition' issues .
If it just needs to be 'gone' (if it was me) I'd think a good deal for a buyer around here (Seattle) would be around a $100.00 price .
I think $200.00 would be a good deal for the seller .
Not really knowing all the little condition issues that exist , I'm just spittin' in the ocean with my guess .
You could always ask for more , if you'd want to .
Sometimes interior designers buy items like this for decoration purposes , though .
Nice old & sturdy-looking gas range , twila briscoe .
I'd add the proviso that the buyer accepts it as-is (you might suggest that they have it 'gone through' by an appliance tech/gas company guy before they put it into service) .
Moving these old units around will disrupt rust & etc. in the gas lines , which can inhibit the gas flow 'where you want it' to go to places where you don't want it .
As sapphire mentions below , this one looks like a candidate for restoration (or a good score for somebody lookin' for major parts ) .
