Morning folks, I've been searching through my vast photo archive! Unfortunately, these photos were taken over a decade ago, and aren't very good.
Sadly, and you may think bizarrely, Sheffield Museums, have, over the years, removed almost all the knives, from their huge archive from public display. They did have an online archive, with photos of some of the knives they hold in trust, and I know it contained better photos of this knife, as I posted a whole thread about the archive many years ago (sadly, sabotaged by BF software changes). However, that archive has been inaccessible for some time now
With access to that archive having been removed, I was unable to access information on the photograph posted above. Fortunately, I had posted an even older thread on Sheffield museum knives, and while the photos no longer display, the text is still there
Unfortunately, typically of Sheffield Museums, there isn't actually a great deal of information about the knife itself
I have some more books, which may contain a photo of the knife
