WOW! Here is an Original D Lens Railroad/Carriage Sunglasses Spectacles Steampunk. Across the bridge is one inch. From barrel hinge to barrel hinge is 3 1/2”. The front lenses are light green. One side lens is light blue. The other is dark green/blue. Someone long ago put tape on the bridge. That was common back then. One of the bows is marked, “B&? Co”. The “?” is possibly an “S”. Not sure. The other bow is marked “Paten’d”. They appear to be made of “German Silver”. A magnet will not attract to them. The tin case is beaten and oxidized inside and out. Surprisingly the push button latch still works! The lenses are not cracked. They do need a good bath. At the edges of a couple of the lenses is some chipping. Most likely from when they were made. Please see photos for condition. A Wonderful addition to your collection. I am shipping internationally through eBay International Standard Delivery. I’ll try and answer any questions as I can. Please be specific on your questions. Don't wait to ask either. Don't miss out! A wonderful addition to your collection.
