Can you identify these floats?
 

Recently acquired by the Queensland Air Museum. They are believed to have been manufactured by EDO. There is evidence of a data plate topside aft of the mooring cleat but unfortunately both plates have been removed. Dimensions are:

Length 17ft 0in
Max Width 32in
Max Height 24in

Definitely EDO - but the exact type is a bit difficult to point to, 44-2425 was 17' long, but this is only a guess.
edit: Strange is the total flat front underside without any sister keelsons

Speak to Kenmore in Seattle as they bought the manufacturing rights I believe and would probably have historical data.

PDF copy of the drawing for 44-2425 here:-

Which on the drawing at the bottom is a note "44-2425 Floats Cessna 180". However the floats on the drawing do not have the curved upper surface that these appear to have.

Thanks to everyone who responded. Unfortunately no reply from Kenmore. The latest thinking is that they are EDO 2130 for Cessna 172 but the file is still open.

It might be worth contacting the Alaska Aviation Museum at Anchorage Preserving Aviation Heritage - Alaska Aviation Museum

They are right on the side of Lake Hood, the largest float plane airport anywhere.

Maybe also try the Bushplane museum in Sault Saint Marie, Ontario. They have floatplanes there and may know something about them.
