Vintage Stetson 58 Gunmetal Men's Aviator Eyeglass Frames

Vintage Stetson 58 Gunmetal Men's Aviator Eyeglass Frames 57 ? Bridge Width and Temple Length I can't make out on the frame arm. Measuring it myself the bridge looks to be 17 or 18 and the temple length looks to be 149-151 . I'm not an expert at measuring glasses so both of these number are approximates.
