Yes indeed, the bore of this "Dunnville oddity" variant, Crosman 150, is as smooth and shiny as a mirror - which made it very difficult to try to get a proper picture of the bore. I have seen, and worked on, a great many Crosman 150 pistols over the past 40 or more years, but have never before encountered one with a smoothbore barrel.

I have been unable to find any mention of a smoothbore Crosman 150 in any of my reference materials, or Crosman advertising literature, so I am inclined to think that somehow this barrel missed the rifling process, and any subsequent inspection process, as the barrel was completed and mounted to the gun.

Another very interesting variation.

Not really in a position to offer any explanation.

I do recall some cheaper smooth bore pistols were advertised as being able to shoot darts, though I am not sure this world led be the case here.

Kind regards,

I have come across several smooth bore Crosmans in my life ( I still own one). The rifles I have owned were not supposed to be smooth bored. I believe this is caused by loose tolerances at manufacture and therefore the rifling 'button' has not touched the walls of the bore.
Sloppy q.c. at Crosman during the 70 ' s is a known factor.
