The catalog dates manufacture to about 1935 and describes the receiver as marked “COLT AUTOMATIC MACHINE RIFLE/MODEL 1925 CAL..30.” The serial given in the descriptor is C102798; the marking transcription reads C-102793. The record states both and does not reconcile them, and neither is relied on here.

The record belongs with the Browning rifles of the Barrow reports: it shows a commercial police variant of the same design, which the catalog says was introduced in 1933.
