Hello!
Your piece of collection sounds very interesting.
Few years back when I was searching something else at the Bundesarchiv homesite I noticed this document about I/SG1:
RL 21/249
Fliegerhorstkommandantur Wilna (E 267/III)
Anlagen zu den Kriegstagebüchern Nr. 4 und 5
including:
"Erfolgsmeldungen der I./SG 1"
I tried direct link to search results at ARGOS (
http://startext.net-build.de:8080/ba...RCH/search.htm ) but it didn't work.
I do remember there was longer description when I last looked into this. IIRC the SG1 report was from Spring 1944. But I may be in error. Anyway the period of the document should fit to your material.
There was also an interesting article about the second Gruppe in Luftwaffe im Focus Special:
Luftwaffe im Focus Special No. 1 - Colour
II./SG 1 in Finland, Spring 1944
http://www.luftfahrtverlag-start.de/...wfspecial.html
I don't know if there was any connection between the I/SG1 and II/SG1 during this time.
If your material includes any mentions about fighting in or above Estonia during Spring-Summer-Autumn 1944 I would like to hear more. It seems that I/SG 1 spent it's time in the Baltic countries Latvia and Lithuania, though.
And if you are not familiar with it, Michael Holm's superb Luftwaffe data site (
http://www.ww2.dk) has also information about SG 1:
