Manufactured in the 1970s. Standard markings and features. Includes original Colt two piece "woodgrain" box marked "J100000" on the end label, test target numbered "J100000", and shipping sleeve with a November 9th, 1972 dated label on the outside addressed to a P.O. box in Connecticut with special note "DELIVER TO RON LACKIE", and hand written in pen on the outside "Mr. Lackie/J100000" and "P.O. put this by Don Mitchell/good for presentation". At the time, Don Mitchell was the Vice President of marketing at Colt. This revolver, being a milestone production piece, would have been sent to his attention for consideration. Don Mitchell would later become President of High Standard, then President of Ithaca, then Mitchell Arms and Mitchell’s Mausers. Although the box and included target are marked "J100000" this revolver is actually marked with the serial number "100000J" and runs in the series of MK IIIs with the letter J before the number. According to Colt factory serial number lists, production serial numbers of MK IIIs reset to a different numbering sequence with the J after the numbers right after this 100,000th gun, making this somewhat of an interesting factory error in that it actually has the J after the number. Comes with a letter of provenance stating this revolver was once owned by former Colt Senior Vice President John Fiedler.

Excellent overall, retaining 99% plus original blue finish with some oxidation on the rear sight, cylinder drag line, crisp grip checkering, and a few minor handling marks. Mechanically excellent. Box is very good with water stains.
