I've had this Boker ground Rohm dagger for almost 20 years. Prior to buying it, I noticed the last digit of the serial number was a 6, while the last digit on the scabbard was a 9; I figured the person who stamped the numbers inverted the last one by mistake, so I wound up buying the dagger. Several months later, I wrote Tom Wittmann (pre-internet days) asking his opinion about the possibility of the last number of the serial number being inverted by mistake; he wrote back saying the inversion of the last number was well within the realm of possibility. My question is: has anyone else had seen such errors on other SS (or SA) daggers? If so, I'd like to hear about them (and see them if pictures are available). Thanks! Scott Here's a picture of the dagger and of the underside of the front cross-guard...
