<p>[QUOTE=&quot;springfld.arsenal, post: 221430, member: 54&quot;]Sure looks just like laser engraving on wood to me.&nbsp; That would make the date of creation later than most guesses so far.&nbsp; I don&#039;t think lasers powerful enough to do that got out of the laboratories much before the 1980&#039;s.&nbsp; The parallel ridges in the burned areas point to laser work.&nbsp; May have been done by computer-controlled laser which would date it even later.[/QUOTE]</p><p><br /></p>
