First, is this a bayonet? It is 13.5" in length, the blade is 9". Markings on blade are ALX. Coppel Solingen with a balance scale. Further down there is a crown with 01 beneath it. There is metal at the end of handle and numbers 40 B 749 under that 1B 1126. In the same spot on the reverse side- 55123. The tip of the scabbard is marked 40 B 749 just like knife. When was this made and for what type of weapon? Actually any info is more than what I have. Thanks in advance!
