SN: 0150DG/0150PY/0150PM. Made in 1976. Colt Bicentennial Commemorative 3-Gun Set. The set includes a Colt Python, Single Action Army, and a Dragoon revolver with accessories. This set, No. 150, belonged to Mr. John Ward, who was the Marketing Analyst for Colt and the project coordinator for the Bicentennial edition. The Bicentennial commemorative was his baby! Included with the set are various letters and paperwork, including the original signed copy of the Colt Bicentennial package letter that was included with each one of these editions, the factory letter noting the details of the set, and the original Colt invoice showing the purchase of the set by Mr. Ward. A neat snapshot into the history of a very collectible and iconic set of Colt guns. Consignment.
