I'm obviously late to the party on this thread. The initial Polizei bayonet posted appears to be a modern reproduction IMHO. These have been around for at least 15 years & some are rather well done, as is this one. Most will be double marked by WKC, the mark lacks requisite detail upon close inspection . Although detailed, the hilt will lack much of the superior detailing of the original 3R/Weimar era Polizei bayonets. The examples that are slotted will exhibit an elongated mortise button, as this one does. The grip emblem, slough aluminum like originals, lacks the detail or a period produced piece. Some will show grey color wood grip plates & others will have newer looking stag. Many are an amalgam of period & modern parts, some are outright reproductions.
