It's a great find. If I ever get the chance on a Featherweight I hope it's and early one. I like the art deco decore on the chrome plate before they turned to the striped or painted side plate; a bit silly really but that's how it is. My hope is a 201 with potted motor and similar decor on the plates
A trick with the smelly box is to leave the lid open in a dry heated room, or even outside on a nice day. Charcoal bags or silica bags helps. For some reason they seem to air out after a while with a bit of effort, but I read lots of complaints on Featherweights being stored a way with the lid closed. I had a very smelly buttonholer box, it took about a year before it aired out; I had it on a book shelf, box open with the lid next to the bottom half.
