<p>[QUOTE=&quot;mynamespat, post: 2652036, member: 83738&quot;]Aye, I reckon I will need to get a scope for RPMs.&nbsp; Holding a loupe while taking a photo is darn near impossible.</p><p>The only reason I didn&#039;t conclude it was RPM#7 and move on with my life is RPM #7 goes NE with a clearly detached D; whereas, the example I&#039;m looking at goes straight east (<i>maybe</i> a hair south even).&nbsp; In hand the D/D-east doubling looks identical to examples of S/D without the clear loop to the NW.&nbsp; The location is spot on as well.&nbsp; </p><p>Is it possible when the D/D was punched over the S the remaining parts of the S were filled by the metal moved by the punch?&nbsp; They polish the area over and it looks genuinely ok.&nbsp; Later, while in operation, the metal that has filled the NW loop detaches?&nbsp; Is that in any way possible or is that some woo woo?[/QUOTE]</p><p><br /></p>
