Vintage Silhouette M1156 20 C 1713 SPX Eyeglasses Frames 55 。Vintage Silhouette glasses frames. Details on arm are: SPX M 1713 /20 C 1433 54 – 12 130. These are plastic with demo frames in them, so they’ve never actually been used. Made in Austria. They feature black arms, gold tone accents, and black and white on the outer edges of the frames. My grandfather owned an eyeglasses shop in the 1980s/1990s, and these were leftover from then. Although these have never been used, they do have some tiny marks (dots/scratches) on the gold tone parts on the arms and frame edges from being in storage. I had to zoom in quite a bit to show them in pictures. However, the frames still look really good overall and have been cleaned to the best of my ability.
