The first actual Model 99 Japanese antivehicle/antitank mine I have ever had. This was in a large group of ordnance given to me and I am happy to have it. I have had several of the US made ones for the WWII era mine training kits. They are a really good reproduction, but still a reproduction. I have since placed plastic filler blocks in it to maintain it's shape. Unfortunately it did not come with the original carry pouch though, but I am not complaining.
