Hi Zamo, Military Mauser Magazines didn't have Waffenamt Marks (Inspection Marks) until 1940 with the beginning of the "122" Marked Magazines and then later in the "fxo" Marked Magazines. Both of these were WaA Marked SE/37.
Both of your magazines should have the spring guide feature. Perhaps someone disassembled one of the magazines and forgot to put the spring guide back in place. There is a small detent machined in the bottom of the follower to accept the spring guide.
Hope this helps!
