Dean,

Yes, I think that is the case.

The Rohm inscription daggers were some of the first to be distributed in the spring of 1934. Rohm was killed on July 1, 1934, and the order to grind his name off the presented daggers went out shortly afterwards. I don't see any intact Rohm daggers being presented after that date.

The only thing that might have happened is that the factories who had stocks of unused Rohm blades completely ground off the inscriptions and then used them in new daggers.

Hope this helps.

Dave
