Here what I have observed:

- The benchmark numbers were used on many (not all) early Eickhorn SA and SS daggers. The numbers were 0-9 and NO number is associated with any particular dagger type.


- The trademarks with benchmark numbers are the large early oval (both types) and alter small oval, also both types. Again, both SA and SS.

- Himmler inscription SS daggers have them as well although they were made for a much longer period.

I have seen numbers in various places on other SS/SA daggers, but not of the type noted above that is close to the blade or sometimes partially under the blade.
