E Tool
 

Could I get some help with this tool Is it authentic, is it an Erfurt and if so would it be an appropriate match for a 1912 Erfurt.
Thanks in Advance

It looks like a DWM 4 lobe crown/F to me. Erfurt tools were not blued. An Erfurt tool is shown below.

Thanks Norm I appreciate your help I am still learning and having the comparison helps immensely. If we were in close proximity we could discuss it over some Sunday liquor. Take Care

More information on the Luger Mag Loading tool
 

Your tool is a 4 lobed crown over an F. It is a DWM tool,1912 to 1914 it best called an acceptance mark. If you want more information at no cost I will send you by Email a 33 page document that will provide information on tools from 1900 to 1946. E mail me at davidolindsay5@gmail.com. The best to you.
