As for 67% Cu... what is brass made of? Link to comment Share on other sites More sharing options...

It's a quality control thing. Link to comment Share on other sites More sharing options...
Astro Posted 8 October , 2019 Author Share Posted 8 October , 2019 But why the number 60 and what does it mean that the mark is "quite subdued" Link to comment Share on other sites More sharing options...
jay dubaya Posted 8 October , 2019 Share Posted 8 October , 2019 (edited) The brass is made from 67% copper and 33% zinc. The 60 below AWDr is an inspection mark from the manufacturing workshop. It being subdued is referring to the stamp not being as indented as the other stamps on the case. J Edited 8 October , 2019 by jay dubaya Link to comment Share on other sites More sharing options...
