The bulk of currently available 7mm VZ24 rifles were imported from Brazil. They were a special light weight version (known as VZ24 JC) ordered around 1929-1930 by China but not paid, so they were rebarrelled to 7mm and sold to Brazilian revolutionaries, then either intercepted or captured by the Brazilian government. These, as well as other models, were later marked with a PM prefix number by Brazil on the right side of the receiver. The post below is from the sticky "Mausers, Only Mausers" which contains a lot of good information on all kinds of Mausers. Attached Thumbnails
