<p>[QUOTE=&quot;say_it_slowly, post: 4425235, member: 50&quot;]I haven&#039;t looked for a bottle like yours however this is a very good and in-depth site for bottles primarily made in the US. They address why it&#039;s difficult to use such information when trying to apply to foreign bottles if that&#039;s what yours is. The site you linked to is in the US and seems to use SHA as a source.</p><p><br /></p><p><a href="https://sha.org/bottle/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://sha.org/bottle/" rel="nofollow">https://sha.org/bottle/</a></p><p><br /></p><p><a href="https://sha.org/bottle/faqs.htm#Why%20are%20only%20bottles%20produced%20in%20the%20US%20covered" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://sha.org/bottle/faqs.htm#Why%20are%20only%20bottles%20produced%20in%20the%20US%20covered" rel="nofollow">https://sha.org/bottle/faqs.htm#Why are only bottles produced in the US covered</a>.</p><p><br /></p><p><b><u>5.
