During WWII, Uncle Sam ordered nearly two million Model 1911A1 GI .45ACPs, and the Union Switch & Signal company of Swissvale, Pennsylvania made one of the rarest and most sought-after variants. Now, at least seven have popped up at the upcoming auction
These include an “EXP” marked version– one of approximately 100 pistols made by US&S using preproduction slides, receivers and other components that were presented to company officers and employees and coated in a bright blue DuLite finish.
Another prized example is a factory cutaway or “skeletonized” 1911 used for demonstration purposes. Few of these guns were so modified.
