Dear friends and colleagues,
the 11 headstamp is definitely Prvi Partisan/ former Yugoslavia. We have this variation with the year codes between 1951 to 1955 in our databases. I have recently seen it on 8 x 57 IS cartridges.
The Egyptian headstamp is from Shoubra factory. Usually in Russian calibers and 9 Luger.
You can find these headstamps plus currently about 6.400 more in our headstamp database. It took me about 7 seconds to find the above mentioned headstamps.
We also have ~1750 color codes, ~1600 manufacturer, ~1.100 calibers + 4.000 synonyms for them and ~3.400 complete cartridges in our databases.
