The stamp of the pick and ore tub in the shape of a foot in a shield on the E. Schmidt & Habermann's standing breech & left rear lug holds the same position as the "gM" stamps found on many Merkel examples. Maybe it was somehow associated with Merkel's 1916 reorganization as Suhler Waffenwerk. Also I forgot to mention that a few times on the standing breech one will see the pick and ore tub in the shape of a shoe/foot between the letters "GM". The pick and ore tube shape may be encircledd between the "G" & "M".

Kind Regards,
