Number of FAA-registered 337's

[mshac]

Ok here goes. Percentage of Active Airframes by Model.
I used Wikipedia as Kim suggested and if there is a ? after the first number, it means the production of that model was not shown in Wikipedia:

FT337GP = 1/?
337 = 48/239 = 20%
337A = 58/255 = 22.7%
337B = 40/230 = 17.4%
T337B = 19/?
M337B = 34/?
337C = 32/223 = 14.8%
T337C = 15/?
337D = 43/215 = 20%
T337D = 7/?
337E = 20/100 = 20%
T337E = 6/?
T337F = 4/?
337F = 23/114 = 20.2%
T337G = 117/292 = 39%
P337 = 2/?
337G = 98/352 = 27.8%
P337H = 33/64 = 51.6%
337H = 10
T337H = 24

Out of the available data, the P337H far outstrips all other models with over 50% still active. The runner up is the T337G at 39%, which is the predecessor of the P337H. The 337G comes in third at 27.8%. The average for the rest of the fleet is below 20%.
