Sharp Shooter and JOLOAR pistols Vfy
The Sharp Shooter automatic pistols were of a simple blowback type which followed the design shown in Spanish Patent No. 68,027. The JO-LO-AR pistols are of the same design and bear the same patent number, with the addition of Spanish Patent No. 70,235. The former patent covers the design of the pistol, while the latter covers the addition of a cartridge case extractor, which was granted to Jose de L. Arnaiz on September 12, 1919. It is conjectured that the name JO-LO-AR was derived from the name of this patentee. Since these pistols are essentially alike, except for the extractor, they are being considered together. Both were made by Hijos de Calixto Arrizabalaga of Eibar, Spain, according to the Spanish Ministry of Munitions and the Eibar Proof House. The Sharp Shooter was marketed by Ojanguren and Vidosa, whose monogram appears on the grip pieces, and also by Hijos de Jose J. Aldazabal.
The Sharp Shooter is known to have been made in 6.35 and 7.65 mm. calibers and may have been made in 9 mm. also, though none have been seen. The JO-LO-AR was made in 6.35 mm. according to the Spanish Ministry, but none have been encountered. It is stated by the Eibar Proof House that it was made in 7.65 mm. as well as in the 9 mm. model, which latter has been seen. This specimen bore the number 5928, the date 1924, and both of the above-mentioned patent numbers. The extractor, which particularly differentiates the two pistols, is shown in the photograph of the pistol in Part IV.
As mentioned, the Sharp Shooter is of the blowback type, having an external hammer and a fixed and exposed barrel which is hinged at the forward end. By pressing a catch, which releases the barrel, the rear end may be tilted upward for examination, loading, or cleaning. The top part of the slide is, obviously, cut away for the entire length of the barrel. The force of the recoil is largely absorbed by the usual spiral compression spring, housed under the barrel, and by the inertia of the rather heavy slide. The arm is very sturdily built and rather heavy for the ammunition used. For example, the 7.65 mm. model weighs ca. 763 grams, or nearly 27 ounces.
The dimensions of the three models are given in Table 47.
