My guess is not many will be sold but what the heck, at least they are providing a kit. A lot of new Ham's don't have a good junk box so they may go for it and maybe get hooked on the old stuff. Most Ham's that do this kind of stuff do it for the fun and fully realize not much money to be made. Some are retired and its just something fun to do.
I also enjoyed the article on the AC-1. I was very fortunate a few years back when a good friend of mine gave me his AC-1. It needs a little work but is in pretty darn good shape. Sometimes the real simple PW rigs are fun to play with and if you like CW like I do, you don't need much power to make a lot of QSO's. I am using the AC-1 with the Heath AR-3 receiver. I did not see that receiver rated on Jay's W1VD receiver performance chart! I can't imagine why
