It's quite simple if you just check his website as I suggested...THOR (Ted Green) is a man of integrity...a scarce commodity in today's marketplace.

Here is a quote from his website and a photo:
</font><blockquote><font size="1" face="Verdana,Tahoma,Arial,Helvetica,Geneva">quote:</font><hr /><font size="2" face="Verdana,Tahoma,Arial,Helvetica,Geneva"> I ALWAYS add a rework mark, to alert a potential subsequent buyer that it is no longer an original Luger. It may look original thus the reason for adding the rework mark, to try and prevent any problems with the buyer knowing it is original or not. The small innocuous mark I place on the bottom of the stock lug is to note that this Luger has been reworked and is no longer an original. Really both the buyer and seller benefit from this in the long run. DON'T ASK ME TO OMIT MY REWORK MARK, because I WON'T OMIT IT and I wont argue about it! </font><hr /></blockquote><font size="2" face="Verdana,Tahoma,Arial,Helvetica,Geneva"><a href="http://members.rennlist.com/lugerman/thormark.jpg" target="_fullview"><img src="http://members.rennlist.com/lugerman/thormark.jpg" width="400" alt="Click for fullsize image" /></a>
