Curtiss Model F

The Curtiss Models F made up a family of early flying boats developed in the United States in the years leading up to World War I. Widely produced, Model Fs saw service with the United States Navy under the designations C-2 through C-5, later reclassified to AB-2 through AB-5. Several examples were exported to Russia, and the type was built under license in Italy.

Design and development

In configuration, these were biplane flying boats powered by a single engine mounted amongst the interplane struts and driving a pusher propeller. The pilot and a single passenger sat side by side in an open cockpit. The wing cellule was derived from the Model E landplane and was of two-bay, unstaggered, equal-span construction with large ailerons mounted on the interplane struts and extending past the span of the wings themselves. The earliest examples of this design were built and sold by Curtiss in 1912 without any designation applied to them; the Model F name only coming into use the following year. Confusingly, Curtiss also used the designation Model E to refer to some early machines in this family, although these were quite distinct from Curtiss landplanes that bore this same designation and all but identical to the Model Fs.

Savage Model 64

Formally known as the Cooey 64, the Winchester-Cooey Model 64B and the Lakefield 64B, the Savage Model 64 series is a semi-automatic .22 LR rifle made by Savage Arms in Lakefield, Ontario, Canada. It operates on a simple blowback action. It is targeted towards beginning shooters, small game hunters, and budget minded plinking. It is one of the most popular plinkers in the United States due to high accuracy, being chambered in cheap, common, and readily available .22 long rifle, and the inexpensive price.

It is unusual among semiautomatic 22s, and traditional (non-bullpup) semiautomatic rifles in general, in that it is available in a true left handed version (left handed safety, charging handle and eject -presumably wrong handed twist). Some consider this particularly helpful for new, especially young shooters, as it leaves them free to focus on more important matters to learn.

The "64 series" has sold under [combination of manufacturers' names listed above] [62, 64 and 954] [one or more letters]. It was also sold as Sears Roebuck & Co. Model 6C. Although often unexpressed in speech, as a "64" it is almost always followed by a single series letter. "64" without a letter indicates the first year of manufacturer only. That version had a plastic magazine. It is considered undesirable. It was followed by the 64B.
