surely a No5 scabbard is cheaper than the full length 07 scabbard?? I wouldn't cut down the leather scabbard unless the removed part was beyond help. shortening the scabbard makes you a Bubba and this question will then come up more often. Short 07 scabbards turn up often enough as it is. I have an Indian SLR long bayonet and it came in a shortened 07 scabbard, if you do it it makes finding the truth more difficult unless you mark the scabbard to show its not original.
