Can anybody offer any information on the rather unusual markings on this PmK round please? I appreciate that with a headstamp date of 1934 this is very early production for a PmK which I understand was adopted in the same year. However, I have never seen another PmK with a red stripe of this dark red colour. Even more confusing is that the same red lacquer is applied to the base of the bullet. Normally the bullet base is sealed with solder.
