I recently purchased a repro. Krag three-piece cleaning rod set from Numrich for about $17.  They had sent me a coupon that pretty much covered the postage.  My intention is to carry it in the butt-trap of my 'range gun'.  Today, I got around to comparing it with an original.  (I have gotten a bit suspicious of the "originals" that are always for sale on ebay by a couple of vendors).  In the attached photos, the original is at the top.  Years ago, I got the original along with a muzzle/sight cover and oil bottle for $15 at a gun show.  Fortunately and ethically, the repro. has dimensions that differ from an original.  Original:  Main rod diameter=.200 inches.  Max. thread diameter=.158 to .160 inches. TPI=30.  Reproduction:  Main rod diameter=.195 to .199 inches.  Max. thread diameter .152 to .155 inches.  TPI=32.
