<p>[QUOTE=&quot;coleguy, post: 730967, member: 9167&quot;]Very nice. Thanks for posting pics. I believe the first two pics are ore crushers. That giant wheel turns a system of pistons, which you can see there are five, so it&#039;s a small machine, which are attached to basically large hammers that crush ore to powder to extract metals. I imagine that was left over from the assay days of the mint.</p><p>Guy~[/QUOTE]</p><p><br /></p>
