The pillar above the batteries container had holders to take one or two flash bulb. The synchronization was via the rotation of the shutter speed dial when it was released. The switch arrangement is slid into the accessory shoe and was engaged with the shutter speed dial by means of a cap which fitted over it. BTLOO fitted Leica II, III and IIIa Illustrations : a BTLOO fixed on a Leica III with byside an another one with the large capacity batteries container BWOOG (for professional use) and the genuine red cardboard box, Leitz, Germany Leica Blitzlicht - Auslöser embossed in gold. some details about the BTLOO : front rear : with the view on the special attachment in the accessory shoe : the shutter speed dial cap stored on top of the pillar : I wish you all a Merry Christmas Edited December 18, 2012 by jc_braconi 10 Quote Link to post Share on other sites More sharing options...
