This set is new old stock. This knife is brand new still sealed up in its original packaging from the 1960’s. This knife has sat in a warehouse for 60 years. The knife was made by Imperial right here in the USA. I have a couple of these sets of knifes and scabbards so I opened on so you could see the knife inside. Yours will come still sealed in its original packaging. The knife is new old stock as you can see in my pictures. The knife will attach to the end of your rifle. These are new old stock but do show storage ware. As thy should for being 50 years old. I have a few of these knifes and scabbard sets so the issue dates will radge in the early 1960’s 1961 and 1962.
