WWII British Army No. 4 MK II BAYONET, SCABBARD, FROG! - eBay (item 310053078800 end time May-27-08 19:29:28 PDT)
This WWII British Army bayonet is marked, "No. 4 MK II" on one side with LB monogram for the Long Branch manufacturer in Ontario. The other side is marked with what might be an N, up-pointing arrow, and what might be a 7 or Z--or NTZ? Or NT7? It's also embossed "75" two places and also lightly etched as if someone wrote 75 and it left a mark.
The metal scabbard is marked, "No. 4 MK 1" on the opening end. I see no markings on the heavy canvas frog either because there aren't any or they're covered with filth.
I'm not sure how the bayonet and scabbard fit into the frog. Another eBay seller had a bayonet like this and said it was for an Enfield rifle. Another seller said it was for probing mines which explains to somewhat screwdriver shaping on the tip.
