Restoring an antique strike-pump air gun

[greenwayjames]

Hoff is Danish.

At the intro of chap three, Hoff explains how he came to use the term "strike pump."

'Systematically different from the bellows gun is a type which is generally called a spring gun, where the momentary air pressure is created by a spring-propelled piston rushing forward in a pump-cylinder. The term spring gun is rather unsatisfactory as it ought to indicate a gun where the projectile is expelled by the direct action of a spring. In the following, the gun with spring-propelled piston will, therefore, be called strike-pump gun.'

Thanks. That explains it. It was the strike part that threw me off. I thought it referred to the energy from the spring being being passed to the projectile by way of a stiff rod

Hoff closely follows Wolff, so, he tends to be a stickler for terminology: see Wolff's Air Gun Batteries.

By the way, there are very few proper antique air gun references available. Hoff's work and Wolff's are absolutely essential. Not much else is.
