<p>[QUOTE=&quot;springfld.arsenal, post: 50026, member: 54&quot;]R U sure it isn&#039;t brass?&nbsp; The caked-on white oxide does look like what we often see on pot metal, however look at the letters stamped or rolled into the inside surface?&nbsp; They would probably not have gotten there if the piece had been made in its present final shape before marking it with those letters.&nbsp; The item was manufactured as a flat item (probably by a stamping press) and either simultaneously or subsequently marked with letters &quot;PN&quot; (probably a manufacturer&#039;s initials) then bent in the final box-end shape.&nbsp; Brass can be bent like that; pot metal (largely zinc) lacks the ductility to allow it to be bent like that without breaking.&nbsp; Just kinda wondering here, I don&#039;t really know.[/QUOTE]</p><p><br /></p>
