These cartridges were loaded at the Fábrica Nacional de Toledo, a Santa Bárbara plant. The bullets were manufactured there also.
This was an order from the spanish police, which provided some samples of Geco Action cartridges. The adventure ended when Geco representatives found out and Dynamit Nobel sent their lawyers.
The cartridges were a faithful copy of the german Geco Action, and were packed in standard military boxes, but the “NATO” word was covered with an adhesive paper saying “ACTION”. The caption “Para pistola” (for pistol) was covered too, with a white adhesive paper.
