I didn't think I'd come back to this thread, but I found another frame, a shogun, that has similar lugs to the one I was trying to identify. The shogun is more of a touring and much heavier frame, but the head lugs look similar, except for the cutouts. Anyway, I have no idea if this means the other frame is likely a shogun but I'll try to add some pictures and a link in case anyones interested
