I came up with 3.65:1 by just counting the flange bolts going by while I turned the wheel.  One of the things that fooled me into believing it was a Marina (3.63:1 being fairly standard.  I will have a look for that tab.  I bet this is a 3.7:1.

I'd like to go for the 4.1:1 gears if I can find them.  Seems unlikely that I will find a 4.44:1, but I'd be willing to put it in.
