Currently I am working on a project with QGIS (2.14.1). Therefore I need to add old (but important) shapes that were drawn by a colleague.
Somehow most of the .prj-files are missing - I don't know why, maybe they were deleted by accident or not created at all. Those shapes with mising prj meta-data are not displayed correctly, depending on the CRS I choose for them they eather appear on a random place on earth or are not displayed at all.
I don't have a clue what I can do, is it even possible to fix that somehow? Maybe via reprojection or something?
I don't know the original projection btw.
The project area covers parts of Southwestern-Germany, County of Rhineland Palatinate, close to Mainz. Based on that I created prj files via spacialreference.org for potential CRS (eg. EPSG 31466, 31467, 3044, 31493, 3857, 32632). Unfortunately without success.
Layer extent: xMin,yMin 3430186.73;5517809.87 : xMax,yMax 3443672.61;5529390.81
