Ww1 german 105mm howitzer quadrant id.

[ArtilleryManiac1916]

Hello guys , planned to buy this one , but not 100% sure for its legitimity to the period of ww1.
Is this a variation , or a Reichswer model that is made from the old quadrant ?
Regards.

The moving part wich indicates the angle seems like it was taken from 77mm german quadrant .

Here is mine (plus two from an online search), there should be a makers mark on it. Mine went to Turkey and it was likely common to many guns, export and otherwise.
