Got this frame for free, guy said it could be a Deluxe, but from some googling doesn't seem to match anything. S&M sticker is obviously tacked on, but welds look like they could be hand welded, but not sure. Some unique details is it has a spanish BB, downtube gusset, chainstay wishbone, seatstay brake mounts and the seat tube has weight saving cutouts. Any ideas?
