W. H. B. Smith & his argument for the superiority of CO2 rifles

[45flint]

W. H. B. Smith Book “Gas, Air, & Spring Guns written in the 1950’s was a awesome window into the golden age of vintage airguns. Well written and very detailed analysis of the guns of the day. As a vintage collector I seem to be stuck in the 1950’s especially with rifles. My favorite spring gun is my mid 1950’s Webley Mark 3 (Smith rated the highest) which I acquired last year. I have since acquired the American CO2 rifles contemporary with it. Crosman 160 and 400. Smith argues for the superiority of CO2? Very interesting argument and one I can test for myself. Interested in the thoughts across the water, Smith I believe was a American author but very well thought out.
Here are my test guns and Smith’s thoughts:
