It seems that previous trips abroad have succeeded by luck rather than design.
The concerning thing is not the lack of knowledge at the check in desk (as it's unfeasible to expect them to know every intimate detail of every law) but there seems to be no point of reference for them to establish the facts. So, whether you are allowed to check in your gun/knife/snake/racing pigeon seems to depend entirely on the opinion of the duty manager.
Even prior discussion and assurance from customer service seems to be of no use whatsoever.
