Questions about Sprengpfeil MM

[napesica]

Hello, I have looked thru many of the other posts about the Willy Sprengpheil MM . I did post a picture of this last week , but it was not under the topic of the MM.
Opinions on this mark, and I will add a couple of photos of the vents on this cap too.
Thanks for any help. Norbert
