The International Cessna 170 Association

Does anyone know who holds the STC for installing Edo 2000 floats on a 170b ? or what the number is ??
I've been searching the FAA's STC database and I can't find anything.I've searched by make,by model,
by name ,can't find a thing. ( even cussin' don't help )
Thanks...............

EDO 2000 floats are approved under the C-170 type certificate (Item 209) so no STC is required.

I should have asked here first, would've saved myself some time,although it made for
some interesting reading.
Thanks for the help Doug...............................Jim
