Collectors have long known that barrels made by Buffalo Arms, Rock-Ola, Inland, and Saginaw used the

Inland-designed separate “swaged on” gas cylinder, whereas Underwood and the other barrel

manufacturers used the Winchester-designed “integral” gas cylinder. What is not so well known, is that

variations exist among the integral housings, depending on the milling machine used, the sharpness of

the cutters, and the technique of the individual worker. The fewer cutting operations that were needed,

the faster and less expensive the part was to fabricate.

Marcus Rust has submitted the four photos below, showing marked differences in the forward edges of

Underwood gas cylinders. Note the progression of fewer milling cuts. Here’s something else we can

take note of, and obsess over !
