The Navy Colt, by Frank Gruber, from Johnny Fletcher Mystery (NBC) aired on March 25, 1946 starring Albert Decker and Mike Mazurki. Book agents Johnny Fletcher and Sam Cragg find their low finances and the Chicago winter incompatible, so they accept an offer of $10.00 to punch James Maxwell in the nose. When the deed is done, the debt remains unpaid, the two are accused of Maxwell's murder, and the only thing which stands between them and destitution is an antique colt revolver.
