I need help understanding this cartridge. It is a 11.5 x 57Rmm Spanish Reformado. I am having difficulty interpreting information on the headstamp.
I am interpreting the SA to mean manufactured in Cartagena, Spain. However, I have read SA to also be interpreted as Subsecretaria de Armamento.
Question 1: What does SA mean - is it both of the above?
The other difficulty is interpreting the two-digit year (if it is a year) on the headstamp. Originally, I interpreted the date as 1918, but now I am not so sure because it might also be 1878 or 1898. The 1 on the two digit date does not look like the 1 at the bottom of the headstamp and the difference could be due to a broken bunter or the like.
Question 2: For someone who is familiar with this ammunition, what is the likely two-digit year on the headstamp?
Question 3: What does the solitary 1 mean?
Thank you for the time to help me.
