<p>[QUOTE=&quot;Jimski, post: 2668431, member: 77373&quot;]Let me see if I can explain the logic of my study: </p><p><br /></p><p>1)&nbsp; On a type 2 SLQ, the date will wear off before the pedestal will wear off. </p><p><br /></p><p>2)&nbsp; On a type 3 SLQ, the pedestal can be completely worn away, but the date can be still visible, as shown in the 1929 example from my first post.&nbsp; This says the pedestal will wear off before the date on a type 3 SLQ.</p><p><br /></p><p>3)&nbsp; Therefore, if you can see a pedestal and no date, 1) says it can be a type 2 SLQ, 2) says it cannot be a type 3 SLQ because the date would be visible.&nbsp; ….&nbsp; Therefore the SLQ is a type 2.</p><p><br /></p><p><br /></p><p>That said, it is possible for a type 2 SLQ to have both the date and the pedestal worn off.&nbsp; My method will not work on these.&nbsp; This leaves the determination of a type 3 SLQ ambiguous.&nbsp; How do I tell a type 3 SLQ from a type 2 SLQ with both that date and pedestal worn off?&nbsp; Maybe by comparing type 3 SLQ (w/o date. w/ pedestal) and unknown SLQ’s w/o date and w/o pedestal with similar wear to see if a pedestal should be there. </p><p><br /></p><p><br /></p><p>Using my logic, I have picked out the type 2 SLQ from Seattlite86’s photo. See attachments.&nbsp; </p><p><br /></p><p><br /></p><p>I hope this helps.[/QUOTE]</p><p><br /></p>
