Export of antique Arms

Question

I have contacts both in the US and Canada wishing to buy antique arms (flintlock and percussion) from the UK.
These arms are exempt from any form of licence in both countries and the UK. They may be freely held as collector’s items or curios.
I was looking towards getting an OGEL but not really sure that applies for occasional one off, low value, shipment. Even with that in place it would still leave the logistical issue of shipping.

The main difficulty I’m finding is a route out of the UK as it appears no carrier will take such items despite the fact they may be 150-250 years old and inert. They fall under the carrier’s definition of "firearms" despite being exempt from any legislative control.

I need help with locating a cost effective shipment route out of the UK to these destinations.
