Rostock Kaligraph Font

Google Translate says:

I have named this font Rostock Kaligraph, because an unknown calligrapher from a Rostock "SVZ-training workshop" (whatever the abbreviation means, maybe someone can enlighten me?) Has created a document in 1961. Here I found the 17 lowercase and 5 uppercase characters. The rest I hope to have completed stylistically appropriate. So have fun with Rostock Kaligraph!

- Edit: Someone informed with what SVZ means. Actually I could have figured it out myself, "Schwerin Volks-Zeitung", which was, however, set in Rostock and also printed there.
