In the USA and for North America the sole importer for Futaba is Hobbico /Tower / Great Planes Model Distributors GPM in Champaign Illinois so you could order over the Internet or your local hobby shop could get one for you is they order from GPM.

I just checked on the GPM web site and the only click ratchet part listed is FUTM3626 1M14A01001 Ratchet 2DR/CR/VR(2). Your LHS can order it as item FUTM3626 or Tower's part # LXCRAS Both are listed as on backorder / shipment pending. Post a picture of the back side of the gimbal would help. I have a large box of salvaged gimbals and some are Futaba.

That part is not too expensive $4.99 and you can also get springs of several weights for the gimbals.

Not sure how things work for the Brits in Bermuda and importing from the USA.

Maybe someone will volunteer to just put one in an envelope and mail it to you.

Alternate if you can get K and S brass 0.016 thick and 3/16 wide strip make your own. The little V that does the clicking can be done with a small hammer and chisel over a wood block.
