The number 2629 is untraceable and it is my opinion that the this was not the original number as there is a slight trace of another number barely visible beneath the #6. The areas around the numbers are slightly depressed as of a removal of what was once there. .
In Ralf Siegerts SA book ,, it is quoted on page 78 concerning the �Oe� gruppe mark ..�Already before the annexation of Austria intio the Third Reich in 1938,, daggers for SA men who were involved in �illegal actions were stamped with the �Oe� letters.�� What these particular illegal actions were except going against Hitlers wishes not to overthrow that Government,,I do not personally know. I am hopeful that when Tom Wittmanns SA book comes out,, that he will be able to shed more light into the gruppe mark itself. Below is a dossier of Hermann Reschny ,, theSA High Leader in Austria.
I am thankful to Adam 777 of the GDC for helping me with this information concerning the birth of this gruppe and the amount of Rohm daggers awarded to these men.
(founded) 1934 -02-01 in Munich,
SA Rohm inscription daggers supplied to this group: 3,200
I can only speculate the reason why we don�t see a lot of �Oe� gruppe marked daggers is maybe the same reasoning that the removal of the Ernst Rohm inscription on his honor daggers were to remove the memory of the same with the Ostereich Gruppe itself. This is just my opinion.
All this information would not be possible ( nor this thread would have been created) if I have not been fortunate enough to be at the Lakeside and found this rare gem,, when I contacted that Trader guy Paul Hogle. Thanks again 
I am also thankful to the Axis history forum in help with the Hermann Reschnys dossier, and insight into the Hilfswerk-Nordwest gruppe.
