Самозарядная винтовка ZH-29 была разработана в конце 1920х годов на оружейном заводе Ceska Zbroevka в городе Брно известным конструктором Эммануилом Холеком (Emmanuel Holek, отсюда и название ZH-29 = Zbroevka - Holek, 1929). Винтовка была разработана под патрон 7.92х57 Маузер по заказу Китая, который и стал основным покупателем этих винтовок. Винтовки ZH-29 выпускались с 1929 по 1939 год, их выпуск был завершен с оккупацией Чехословакии Германией и более не возобновлялся. В первой половине тридцатых годов винтовки ZH-29 под самые разные патроны широко испытывались в разных странах, включая США, однако заказов кроме китайского так и не поступило. Тому причинами стали сложность изготовления и высокая стоимость винтовки, а также ее чувствительность к загрязнению и ненадежная работа в тяжелых условиях.

Винтовка ZH-29 использует автоматику с отводом пороховых газов в цилиндр, расположенный под стволом. Запирание ствола осуществляется перекосом затвора вбок, за вырез в стенке ствольной коробки. Винтовки ZH-29 выпускались как в самозарядном, так и в автоматическом вариантах, с возможность стрельбы очередями. Питание осуществлялось из отъемных коробчатых магазинов различной емкости. Магазины также могли дозаряжаться из обойм прямо на винтовке, при открытом затворе. В механизме была предусмотрена затворная задержка, останавливавшая затвор в открытом положении по окончании патронов в магазине. Выключение затворной задержки осуществлялось нажатием на спусковой крючок, последующее нажатие на него приводило к выстрелу.  Отличительной особенностью ZH-29 было наличие алюминиевого оребренного радиатора, расположенного на стволе перед цевьем. Винтовка ZH-29 имела регулируемый открытый прицел, на стволе имелся прилив для крепления штыка.

M420S Czech Semi-Automatic Rifle

BRNO MODEL ZK420 EXPERIMENTAL SEMI AUTOMATIC RIFLE
SN 1 WITH SCOPE. SN 0001. Cal. 8 mm.

This Czechoslovakian model ZK420-S was an experimental semi automatic rifle made by the Czech that appears to have incorporated some features of the American M1 as well as similarities to the German K-43. It features a rotating bolt which is with a gas operated recoil system, an adjustable rear sight graduating from 100 to 1,000 meters, and is also equipped with a German style scope. Features a somewhat quick detachable scope mount with rings that are very similar to the US model P-4 with a couple of simple thumb tightening screws. Rifle appears to have a very thin coat of gray Parkerizing on it and is in excellent overall condition. The bolt assembly appears to be a mismatch because it has the number "29" on it but being an experimental it could very well be an inspector mark or a proof mark. PROVENANCE: Stern Collection. CONDITION: Receiver retains 98% of a very thin grayish green phosphate finish with the bbl being similar except with some patina.  The gas cylinder and handguard retaining assembly as well as the magazine and trigger group show significantly phosphate finish.  The upper handguard assembly shows almost new with just a couple of small nicks that you can only see under a very good light.  The buttstock is also in excellent condition, showing only a couple of scratches and one small ding behind the wrist.  The phosphated checkered buttplate shows nearly new with the blued screws almost new.  The telescope shows about 98% of the original blued finish with clear but slightly dirty optics and a very pliable rubber eye piece.  The scope elevation cap shows no finish loss but does have a couple of small dings in it.  It is accompanied by a small pouch with a cleaning brush in it and a cloth sling that show nearly new.  All in all a very fine, what I believe to be, experimental carbine that would be a great addition to a military carbine collection. 4-34057 BK135 (3,000-5,000)
