Welcome to the forum , bremerton .
I'm guessing that your item has been refinished .... This can raise or lower the value , depending on who's buying it .
From your image , it looks pretty clean-lined and functional , even today .
If it's all original hardware & 'chipless' & mostly primo condition , I'd guess that the most it could bring in , in the Seattle area(s) would be through private buyers .
The most I've seen a refinished one sell for around here (Seattle-Tacoma area) was $895.00 , early last year .... buyer was an interior decorator buying it for a job .
I suppose , though , it's up to you to set a price that will at least sastisfy what you're willing to let it go for .
Cool little unit .
