I don't own a full Rolm, so I don't have one to compare it against. I do own a fully ground Eickorn Rolm blade. The logo on mine is closer to the grip crossguard. Also, the Rolm inscription seems to be off center on the blade. These two things would make me wonder if this inscription was added later. I'm sure one of the more knowledgable collectors on this page could let us know if there were some Rolms made with logo so far from the grip.
Just my two cents and worth every penny
