Do any of you that attended Johns Auction in San Diego after his death have or know who obtained a set of o’size cylinders and 1 matching detaching Cyl. head similar to late Evinrude 4-60 or Big Four blocks and are 3" bore instead of 2 3/4? These may have casting numbers "SK-XXX" unknown on them. Jim Ross, Camden, Tn. ph 1-731-584-2195 or new e-mail <sogentiiiky@gmail.com>,
