[Milsurplus] RCA Radiogram forms 1930s ?

[Hubert Miller]

So here are two RCA Radiogram forms I am asking about. One is "Received on S/S" and one is "Office of Origin". Does this mean one form for incoming messages and one for outgoing ?
Just trying to clarify this for my own accuracy in writing about such forms.
The S/S Santa Elisa was a fuel carrier sunk August 1942 off Cape Bon, Tunisia by Italian torpedo boats.
The forms came from a radio service employee of Alaska Steamship Co. in Seattle, so the Santa Elisa must have sometime in the mid 1930s worked the Pacific Coast also.
thanks-
Hue
