Rocker1 may be right: real dagger, repro chain. There are all kinds of repro chains out there these days, varying in quality. For the sake of argument, chained scabbards were in high demand during the period and it is possible, perhaps probable, some SS members had chains made by private contractors or jewelers and fit them to their existing M33 scabbards. Something else that bothers me about this one is the area just above the center band. Such wear and paint loss is unusual in that area. It could have been caused by the center band being slid back and forth to attain a decent fit to an existing M33 scabbard. If someone "dummied" this one up, shame on him! In its M33 form, it is a rare and desirable dagger. He probably thought the dagger was just another RZM type and was unaware of the rare trademark.
