Thanks for all of the advice. Enfieldspares, this was the main thing holding me back as I'm not expecting to replace the cabinet so wondered if it would be better to pay the extra and have it done 'properly'. That being said, I've only found Brattonsound offering left hand hinges and they are over double the price of similar cabinets to begin with. I'm looking at https://www.ultimate-safe.co.uk/6-gun-safe-cabinet-extra-deep-with-ammo-box The nearest Brattonsound equivalent starts at £270 (though it does have double skinned door).
