Where to buy vintage 2 jaw, manual lathe chuck?

[ArtistnonMachinist]

Hello all! I am an artist in need of an affordable, vintage, 2-jaw lathe chuck for a project I am working on. Chuck would have to be manual, preferably something with a 6" spread. Would anyone happen to know of a good source for this type of lathe chuck? I have to find something in good working order, but does not have to be pretty. I've been scouring the web for hours and have come up blanks, so any help would be greatly appreciated. Thanks!
