Another great purchase. This is the 4th piece of inert ordinance I have purchased and I have not been let down yet. I’m always excited when I get a new piece from this seller. This is a 57mm rocket but it is a copy of the S-5 Soviet rocket, an original Chinese copy. I’m still very excited to add it to my collection. Every item that I’ve gotten from this shop has been exactly what I expected and has made a great addition to my collection! Always a great experience. Shipping time was great too.
