Lovely Rifle. Thanks for the link.
For years it was said Texas Ranger Frank Hamer used a Police Model 81 in .35 Remington during the pursuit of Bonnie and Clyde in 1934. The Model 81 was not offered till 1936 though.
There was a model 8(1906-1936) present at the ambush in some of the still photographs after the ambush, caliber unknown and in the hands of another officer. Maybe it was the .35 Remington that Hamer said he used, and in later years it got mixed up and became a Police 81. I have also read somewhere long ago, Hamer liked the model 8 in .25 Remington for shooting at fleeing cars.
The six ambush officers, had some BAR's among them, to counter the BAR's carried by the Barrow gang. Some say Frank Hammer had a Colt Monitor which was a special law enforcement version of the Army's BAR1918.
I read where some of the AP or FMJ rounds fired from those Automatic .30-06's, were shooting straight through the Model A, Clyde, Bonnie, and out the otherside.
.45ACP's were known to deflect and not penetrate at times on the thick car bodies of the day.
