Thanks Guys for the positive comments. Yes, this one is considered a preproduction prototype.
How many were given? Who knows I know that Dave has at least one, perhaps he has an idea?
This one is indeed a ground Rohm with the single oval trademark. The blade was further "dishonored" by breaking the tip. Good eye noticing the scabbard color. The reason it looks strange it that it's a soft copper base rather than steel. This no doubt is the reason for all the bumps.
