There are cartridges that have turned up in Spain and are identified there as dating from the Spanish Civil War based on the ammunition they were associated with. The headstamp code “SPC” has also been identified as Sociadade Portuguesa de Cartucheria. They were previously discussed on the Forum at:
Below are the images of the box and the headstamp.
I was told by a Spanish source when I first obtained these cartridges many years ago that SPC was a Shotshell company that was acquired by DWM or hired by DWM to produce these cartridges using DWM components and a primer made by SPC. A very knowledgeable Portuguese source said a Spaniard told him that they were produced in Portugal between 1936-1940, secretly, for General Franco. Another German source said they were manufactured by DWM and SPC was simply a front company established by DWM as a cover.
Recently I obtained a full box similar to the one above which contained a significant number of these cartridges but headstamped DWM K 480C K. This pretty well establishes the DWM connection, but what was the connection?
Does anyone have any information on these cartridges or on who SPC really was. Perhaps there are corporate records out there somewhere.
Any help appreciated!!!
