This is the beginning of a research project for all of us WWII Converto Airborne Dump Trailer  enthusiasts.   There is a couple of trailers out there that bear the name of the Oxnard Heavy Maintenance & Manufacturing Co. 

The trailers are supposedly the same dimensions as the Airborne Converto Trailer and they are so marked on their data plates.   They are not only sized the same but they look identical.   I am not sure of the specifications that were for the OHM trailer but somehow they got crossed with the Converto.   

If anyone has any information on these trailers, please forward it to me. 

Thanks
