<p>[QUOTE=&quot;springfld.arsenal, post: 9862343, member: 54&quot;]Thanks.&nbsp; One issue is that this object was cast by amateurs in a backyard or something.&nbsp; Only the bigwigs at Alamo are allowed to see the metal analysis.&nbsp; However I suspect the makers were aiming for brass but may have put other Stuff in.&nbsp; Zinc with contaminants such as lead will exude “zinc pest” which for example.destroys many older die cast toys.&nbsp; But they found Formic acid dissolves the stuff.&nbsp; They call it a “carbonate” but I haven’t yet seen the other part of the compound.[/QUOTE]</p><p><br /></p>
