Pretty sure they get stuff through ashdown ingrams I think it is. Have a look on there and see whats up.
The thing is price with most people, they're cheap and don't want to spend $200-250 on a New guard when they can bog theirs and use the money to stickerbomb their gearknobs.
I can state for a fact I've seen brand new guards for ke30 pop up on eBay from to time to time so you may get lucky there, not sure if NOS or repro but
