Tell me about these bayonets?

[TheWhole9Yards]

I ordered these from a site whos name shall not be mentioned. Listed as No4MK1 spike bayonets, can’t help but notice they are all slightly different. Am I just imagining things?

Used them as tent stakes when we were kids , couldn't give them away . Found a crucifix bladed one once( wish I still had it !!) Never did find out where it went to . If there are any markings/ stamps on them they will tell you something other than that its just the difference between makers and difference in casting and finishing process. I remember seeing 45 gallon barrels full of them . If I remember right there were small differences in the locking mechanisms of some of them .

Once you get the grease cleaned off you should find some markings stamped on the large flat areas. Many makers.
