I came across another site where they reference a <em>Reichsbetriebsnummer </em>or RB number. that according to the site was used from sometime in 43 on. Is there a site or a book that would have the numbers, and what cities and factories they reference? Or maybe more simply, which German helmet "bible" would be the place to start. I've seen some comments on books here on the German Helmet Vault noting those books that have been poorly done, or worse become the justification for the increase in forgeries. Is there one that folks would recommend that would fit well on my shelf? Thanks Dan And yes I'm getting a bit of the bug to try and start the hunt for the real deal in terms of an M42, and not get taken if possible. Edited to add a photo of what was considered 'the book' back in the late 70s when I was doing the armor model building and wanted to get things right. Made me laugh when I opened it up again as it only mentioned the M35 and the M43 aka the M42 as it describes the German helmets. No mention of the M40 and the term M42 isn't in there. The photo in my avatar is scanned from that book.</blockquote><br> Upload Files:Add another file ...Maximum files: 10 · Maximum file size: 10 MB · Allowed file types: jpg,jpeg,gif,png,bmp,pdfCancel Share this: Share on X (Opens in new window) X Share on Facebook (Opens in new window) Facebook Like this:Like Loading...
