The circle-N in the lug well is a commonly seen DWM worker's mark.
My commercial-series database lists Swiss Commercial 87095, 87134, 87141. The first one -may- have an upright c/N proof, not confirmed. They are stuck in the middle of a series of 1921-dated 20DWM.
What "leftover" ordinance marks am I missing, besides the Swiss cross on the barrrel?
