Yep. There's an article in the July 1998 Airways about it that talks about the plane the OP is asking about. The USAAF originally ordered 150 sets of Edo 78-29 400 floats for C-47's. Only 30 were ever manufactured and not all were actually installed. C-47s with floats were designated C-47C's.
N130Q was originally a C-53D Skytrooper delivered in October '43, acquired by Eastern in November of '45. Modified to DC-3 standards and stayed in service with Eastern until 1952. Sorry I don't have any info on landing/takeoff, but I do love old floatplanes.
