I have the line of advance of the unit that acquired the helmet, and the dates in which they were in said places. I don't have a specific place of acquisition, ergo the desire for a Rangliste of the Luftwaffe. If I can find a list of Wette's that were in the LW then I have a starting point. From that starting point I can trace the units in which those Wette's were in, and more importantly the locations of said units at certain dates through unit histories when and where they exist. If and when they do not exist I can at least eliminate incorrect Wette's. That being said, thanks for your help mate, I'll try the phone books.
Regards,
R.H.
