I think SA2136CE is an error but thats OK its the first one Dennis has made unlike the many I've made.
By the way nice list on the floats very informative I copied and filed it
SA2136WE,"Sea Emperor, Inc.",Amended,02/15/2001,"P O Box 1326","Sumas","WA","98295","United States","Installation of Tritan amphibious float Model TA3500.","1A8,","ANM-100S Seattle Aircraft Certification Office Tel: (425) 917-6400","Alliance Aircraft Group, LLC\H-295 (USAF U-10D); "
oh, oh can't find STC SA7835CE PK D4000A AMPHIB for H700 but did find SA7835SW
