These are a couple of the resources I have on bayonets. They're not complete. The makers I know of are; Milpar, BOC, General Cutlery, and Ontario. Then there are reproductions. Read the identification stuff to recognize what the markings should be and you'll also be able to determine approximate dates. Ontario was likely the only company making the M7 after the 80s. I believe the last company making them otherwise was BOC or it may have been General Cutlery. One of the two made them in to the mid 80s and those are the ones often found in wrappers similar to the Ontario M7s you have photos of above. There are a few sources these are readily available from here in the states, and in my case as I'm in Ohio, some are almost local. I could drive to pick it up in the morning and be back for lunch. I don't know that they'd deliver to your neck of the woods.
