A superb helme with super markings. Excellent! Recently,I tried to get a thread going with simply pictures of helmet markings as a companion to our makers list. The picture of these PB 23 markings would make an excellent addition to that thread. I also find the older style wider visor trim very interesting on this helme. Brian
According to the Wunderlich catalog you could actually buy a single copy of an old-style trim. So the Kammer workers could have a store of these to repair helmets.
