Franco:
There are many types of markings that can be found on these helmets. The simplest are the regimental markings eg JR24 ( Infantry Regt No 24). You can look these Regt numbers up in reference books and find out the full name of the regiment, when it was formed and where it was based. The other common marking is the Army Korps marking eg BAXIV which is the army korps number for Baden regiments. We have a thread on this part of the web site where we are posting fotos of these markings and descriptions. Brian
