  1. Paint signatures with elements are easily matched if analyzed from a manufacturer. This has been completed with several complex German examples..and extremely accurate I agree wide variables with paint such as white paint with unknown origins on US helmets are very difficult to match because we do not know where the paint came from. But the XRF data is still useful for the database. However, the fakers must understand the basic elements that are present in period WW2 paint. Now... apply technology to understand the non elemental data.. Without taking a sample.
  2. IMHO. I like to see Lead and some other elements in WW2 helmets...German and US... so many fakes XRF is just one tool .....interesting to see when one of the most valuable helmets in the world was discovered http://www.ucl.ac.uk/archaeology/calendar/articles/20100920b The first thing they did was shoot it with XRF S/F
  3. IMHO, regarding US helmets , specifically the highly faked Airborne helmets. XRF is a good reference point but more data is necessary, esp with white paint . The authentic Beauchamp's http://www.ss-steel-inc.com/ss_steel_feature.htm helmet revealed some interesting XRF numbers.
  4. Gentlemen, I started analyzing German helmets starting in 2009 with XRF and have scanned hundreds of helmets from some of the largest collections in the world resulting into a large database . XRF is a very powerful tool in providing the elemental composition of the object without damaging it. This includes the steel, paint, and decals. It is possible to match 5 layers ( steel shell, 2 layers of paint, 2 set of decals ) on 2 different examples of German helmets with no problem. The elemental composition of all the different German decals from WW2 are also now known. In 2010, XRF anal
