Vntg W.j. Watt Daymark Blade Salesman Sample! Wow! Rare! Safety Razor

Offered is a spectacular find featuring what I believe to be a Vintage W.J. Watt The Daymark Blade Salesman Sample!  WOW!  This Salesman Sample is a miniature and quite RARE!  The box is brass and measures about 7/8" x 1".  It is engraved with the following:  "Made By The Makers Of The Daymark Blade, W. J. Watt & Co. LTD.  BHAM England.  The box flips open to reveal a blue felt covered bottom and top.  The top features a large "M" and behind it was a folded envelope.  The envelope reads "Myatt" "Turn It Over After Using" and the manufacturers information with instructions.  Inside this envelope was a rust stained folded paper.  I opened it to find a very cool tiny razor blade.  It is rusty (See pics) but one can still see wording.  With care, this rust may possibly be removed.  The blade measures a little under 3" long!  This antique advertising Salesman Sample is quite RARE.  It is being sold "as is."  A wonderful addition to your collection.
