I have found further images of your fuze in some documents i have of Danish ammunition unfortunately there is no designation , The title says "Dobbeltvirkende brandrÝr ukendt" which i believe in English is "double action fuze unknown"
Attached are the images i have which may be of interest to you.
Thanks for the help. Now i know in what direction I shall look. There are at least 5 different types of double action fuzes in brass made from the 1880 and forwards. I will let you know wenn I find more information.
