BEISTEGUI HERMANOS 1914  The Beistegui brothers started their partnership in 1910 producing 7.65 pistols and 8 mm revolvers for the French during WWI.  When the war ended in 1918 they joined with other Eibar gun makers in making small 6.35 and 7.65 mm pistols.

Beistegui Brothers not only made guns but marketed them made by others.  One of the lines Beistegui is given credit for is the Royal ,but this name was the trade mark of M Zulica circa 1909 so Beistegui most likely bought it from him.  Beistegui is also given credit for the Paramount but this gun is a 6.35   The Royal M31 and the Super Royal M34 sold to China post war. 

This gun is marked 7.65 1914 AUTOMATIC PISTOL, Beistegui Hermanos-EIBAR and has the BH code.

BRONCO Tradename of Echave y Arizmendi, Eibar, Spain.  The firm Echave y Arizmendi was Jose Echave y CIA in 1914, and was a workshop occupying 4 workmen in 1916.  This workshop appears in the Eibar registers in 1917 and reappears in 1918 as , Echave y Arizmendi, with a workshop occupying between 10 and 20 workmen.  Echave y Arizmendi filed the Spanish patent number 66130 on January 7, 1918.  This gun also comes in a 6.35mm version.  Echave was allowed to return to his work after the civil war making bicycles and was allowed to make several pistols in the 50's but they are less well known than the big three.  Basque, Echasa, and Fast are among their works as well as the BZ which was made for a French company.
