Colt ACE .22 LR serial number 7103 (manufactured in 1936 and shipped December 28, 1936) - Blue finish with mother of pearl grips and factory "B" engraved coverage from the shop of Colt master engraver Wilbur Glahn.  The mother of pearl grips were not listed in the factory letter.  This pistol was a single gun shipment to Chas Koehler of Saginaw, Michigan on December 28, 1936.  It was processed on Colt Factory Order number 17324.

Engraving style is similar to Wilbur Glahn engraved Colt National Match serial number C163995 which is pictured on Volume II, page 599 of the Book of Colt Engraving.  It also shares similar engraving style characteristics with Colt Government Model, serial number C147731, pictured on page 603 of the same book.

The total ACE production was limited to just under 11,000 pistols with just 22 pistols having been factory engraved.  In 1936, the cost of the standard blued ACE pistol was $40.75, factory engraving with "B" coverage cost an additional $26.70 and plain factory mother of pearl grips cost an additional $15.00.  The factory enhancements brought the original cost of this pistol to $82.45 in 1936.
