I find all of this very odd.First we don't except MM chained daggers which we now know were originals as there owners kept them and bought a chained scabbard or the vet may have switch daggers because it looked better.
Now we are going to except the wrong MM for a Rohm in a chained scabbard.I remember standing at a dealers table years ago and listening to him say only buy a non-maker mark chained dagger, this way you never have to explain it.I would like to hear from some of the more experienced people on this one and the dagger posted.I am making reference to the dagger on the dealers site.BTW nice dagger and looks like a nice anodized scabbard.I do hope it works out to be something different as new things are aways turning out.
