JR is correct, as usual

The SA prototypes or "Christmas Daggers" were ALL full Rohms.

The EP&S examples carried the well-known EP&S logo set close to the crossguard. The one below is currently for sale by TW.

Note: I have altered the contrast to make the trademark more visible but the grind marks look worse.
