[PSUBS-MAILIST] Old sub built in Chicago

["Michael B. Holt" <mholt@richmond.edu>]

In Popular Mechanics, December 1960, there's a tiny photo and
a caption about a homebuilt.  Page 89, top left.

"Powered on the surface by a five-horsepower engine and
underwater by a two-horsepower electric motor, a homemade
13-foot submarine prowls Lake Michigan.  Isadore Portnoff
and Jerry Krason of Chicago made the hull from a used
500-gallon water tank.  The craft weighs 3000 pounds."

The photo is from one end and above, and shows the
sub lifted partly out of the water.  One end is a 
cone, and the conning tower is a cylinder.  There 
are no visible ports.  A tube extends up from the 
hatch on the conning tower.  There are four
rectangular planes, paired fore and aft.

Does anyone know about this one?
