Good luck with your disposals Trev.
It comes to some of us in the end if we have no one to pass the collections on to. I've been disposing of my collection for several years but still have a few to go.
How are you going to cope with your local PO not willing to handle airguns? Is that a personal decision by the postmaster/mistress, or is it the law in NZ ?
I hope your website continues for many years to come, as it's a mine of useful information and excellent photographs.
