This variation of the Municipal Police Bayonet is difficult variation to find due to it having the larger pommel with the built-in rifle slot. The mortise button works very well, as does the spring. The eagle's head pommel has beautifully detailed fletching crisply engraved on the obverse and reverse. The reverse side of the guard has engraved oak leaves only on approximately one half of the quillion, while the obverse is engraved the entire length. The grip plates are very nice quality antler, with deep gold and brown tones and a creamy tan on the edges. These plates are retained by aluminum rivets with dressed heads on both sides and the aluminum police insignia shows some wear, but is nicely detailed and looks great against the darker grip plates.The black leather scabbard shell is in excellent shape with the standard dual trim lines on the edges. The nickel mounts are also scalloped and are retained by staples. This is one of the nicest scabbard shells I have ever handled! Attached to the scabbard is a black bayonet frog which although still fairly supple, definitely shows its age with some crazing and flaking in a few areas. I had to forego the temptation of trying to remove it from the scabbard to look for markings underneath the frog, but decided to not risk damaging it.The 13", cut-down blade is a very nice example. It has a wide fuller and is in beautiful condition. There is a tiny bit of lifting along the very edge in a couple of areas, but is hardly noticeable and is very minimal. The obverse ricasso is stamped with the Knight Head trademark of the WKC firm," Weyersberg Kirchbaum & Cie Solingen" On the reverse of some these blades one will find the full company name, but this example bears the Knights head logo and initials only. Overall a beautiful piece and the more unusual bayonet lug slot as well makes it even sweeter!
