John, sorry to ask this mundane question but have you thoroughly stripped the bolt? If yes, could you share pictures of the parts involved in the safety mechanism so that we can compare with our civilian models? Correct me if I am wrong but I think the Greek 1903 is built around a short magazine (as the 1900 and civilian 1903, 1905, 1908 & 1910 are); some parts are interchangeable so safeties may also be?
