Hello Oleg, thank you for looking and your statement. I do own this dagger for quite a long time and due to my personal experience and the overall look I always have liked it. But I never habe been totally sure because the load of messed with M29 navy dagger. I am very pleased about your classification and estimation!
Regards,
