Yes, it's highly possible that the caption is incorrect and some of these are in fact N4A's own products.tomschen6645 wrote:These photos just the N4A arsenal of products in 1943 or 1944.
BTW, the book "安徽省军事工业志" contains detailed information on knee mortars, little mortars and infantry guns produced by N4A's arsenals(unfortunately no photos). Worth refrencing if anyone is interested.
