Ed Welch’s Vintage Eyeglasses and Antique Spectacles.
I recently had an antique rimless set of eyeglasses recut for my prescription. I purchased the spectacles on eBay for about $5. Unfortunately, the right temple earhook was broken. I had them repaired, and they are wearable, but the repair work shortened the earhook to the point that they require relatively frequent adjustment.
Perhaps Ed will be able to assist me.
