Fortunately the late 1929-30 Philco lowboy cabinets were sold with a multitude of chassis, so they built a lot of them. It might be an idea to post an ad looking for the legs, and posts from a junk cabinet, I remember Rodney out in Washington found one that had been stored outside under some stairs, but salvaged the chassis, and some solid wood cabinet parts, there may be others out there. Actually the cabinet you have is different from the one Rodney had, so I think it may be a 1928 model console.
