British Naval C1858 Cutlass with german blade

[Cathey]

Hi Guys

I am having difficulty identifying this blade maker, probably german but I cant find this particular design in any of my books. Can anyone help identify it thanks.

References to this pattern are also hard to source as it came in at the same time as the cutlass bayonet. I have seen it refered to as a lead cutter but I am not convinced this is actually correct.

Cheers Cathey
