I heard that they didnt just do the HE crossguard and that they have another mark cant remember what it is so this could well be it??? Regarding the banchmark im unsure if they were all numbered I know most are, mine is numbered 1 but one of the more knowledgable members will be around soon and maybe able to shed a bit more light on the dagger in question. All in all the dagger looks ok to me but im no expert. If you like i can post a few pics of my rohm dedication for you to compare?
