I've had my gently used Cornwalls since about 1979 or 1980 I think. Now due to space limitations in my new condo I find myself having to sell the big beauties. Does anyone have an opinion about what they think they are worth? I've never worried about it because I thought I would own them forever. BTW, I bought them as unfinished cabinets which I put a coat of clear varnish on.
