I paid £30 for my tatty one about four years ago. It was in the grease. When cleaned off I found it was rusty, so had to polish it to mirror bright. Although not 100% perfect, it's not too posh to show some one. Some times if you have an immaculate original bayonet ( or gun) you can become afraid to show it to poeple in case it gets marked. They are tough old things, designed to fight the Keiser, so enjoy owning it.
Best regards, Lester
