Float to shore? Will Mr. Archimede's school principal please stand up? I was about to say the TBX-6 book shows no such foto'd cover but looking at Fig. 58, one might say SHO NUFF! (voila for the int'l set). There's one drawn in in Fig. 58. Cover has screw hook-lugs and wing-nuts. Let the hunt begin Marty ((think I'll put it on a web site))
