As time passed I stopped looking for other matches for this violin, as all known resources published and accessible online had been exhausted. Some instruments, at first glance, seemed to be potential candidates but nothing suited the eye. Then, having learned that the online source I visited most often had acquired the now defunct [Jacques Francais] and W. E. Hill & Sons photographic data bases, my research resumed.
Certain details in the curves of the back outline, though not readily (clearly) visible in the grainy small color photographs, seemed as if they had imprinted themselves in my memory. [Now there is another 'photo archive', Violin Watch (so-called) based out of China or maybe Taiwan, wherein I first saw the set of images which I recognized as the same one in the images sent to me. This set was in a section which I later discovered corresponded with the images from the Jacques Francais archives.]
After downloading the set, I began to create montages until each frame of the respective backs were of the exact same size while attempting to place each image in the same position, horizontally and vertically, within each frame: even though in the more recent color image the back of the violin was standing more to the vertical; while the older b&w image showed the back leaning away from the camera.
The first montage is the final result of superimposing one frame over the other.
The second montage depicts the backs side by side.
As can be seen they are one and the same.
