Hi Wally and thanks for your reply,I will pass Joes details onto the owner.
I have now sent the pictures to Mitchell for posting.
Let me put the question of value another way,what would collectors on this forum be willing to stump up for this pair of knives if they saw them on the open market.
There are a host of cool knives in the throwing knife section in the museum,it makes you realise that there is probably a few more 'hidden gems ' like this out there.
