Reference guide

Watch references by case diameter

Every reference here, grouped by the diameter its maker publishes. Diameter is the figure buyers ask for and the weakest predictor of fit — pair it with lug-to-lug before you promise anything. Rectangular cases are absent by definition: a Tank has no diameter, and its two case dimensions are given on its own page.

91 of 96 references carry this figure. The other 5 are absent because their makers do not publish it — not because it is unknown to us.
