7x57 Mauser with headstamp DWM K K

Sorry for stupid question, but what is a meaning of “K K” in this headstamp - Karsruhe or 1936 (year)?

Never a stupid question…especially with DWM as they seem to have more headstamp variations and code changes than grains of sand on a beach. When DWM used the KK date code they were small letters used in addition to other markings. When they used the large date codes they were two usually different letter such as K W, K V etc (Except for BB, CC, D and EE). So I would say with 95% certainty your headstamp refers to the standard KK for Karlsruhe.
It looks like a 7mm mauser made for Spain for the Civil War.

Thank you very much!
