USN,
I can tell you that the name is 100% LOHMANN from a 9th Companie. Unfortunately the guy did not mentioned the unit number behind the company...
But it´s true, we have a BA.V. stamp which is silesian and west-prussian. The unit stamp on the left side of the neckguard is unfortunately illegible. The other side shows a stamp 2.K (2. Kompanie). It is possible that the helmet has changed the unit at some time.
Here are the active units of the AK V that have worn such infantry Haubes: JR19, 46, 47, 50, 58, 154, 155, FR37 and finally not to forget the TB5 (or Tr.A.5 in war time). Does the spike unscrew? Then it would speak for the TR.A.5 (Train Abteilung).
Maybe you can try to slightly wet the markings on the rear visor and make better picts, because LOHMANN is a very common name in Germany....It´s good that we have his company number but to track him, we absolutely need his unit...
