Didn't Frank Hamer use a Model 8 to gun down Bonnie and Clyde?
His son once said he did, but the gun he provided was made several years later than Bonnie and Clyde being gunned down. I'm thinking Hamer used a BAR..
One of the deputies did have one, it's in the Morphy's link above. There are pictures of guns atop B&C's car that show a model 8.
