Collector or shooter ammo?

[Cyo]

I've got some old Kynoch ammo in .404 Jefferies that I bought many years ago when I actually had a .404. I believe Kynoch stuff is being made by Eley now but this is the old stuff, not a recent manufacture. Being big bore ammo, even new it's expensive so I'm wondering if this has more value for collectors or shooters?



(Shown with a .44 Magnum for scale. The '.404' actually uses .423 bullets...gotta love ammo naming.)


I just started researching it and I found that I missed an ammo collectors show in Lancaster that was a couple of weeks ago. I'll see what I can learn at the King of Prussia show and the Allentown show, but I figured I'd ask here first.

looks kinda like a fat 30-30, do you happen to know the manufacture date?
