Vintage Rolex Pocket Mirror authentic 1918

Product Name: Vintage Rolex Pocket Mirror authentic 1918
My maternal Grandmother was given this in 1918. The Silver mirror has an "F" or an "E" (Francis Elizabeth but she went by Eliza) on it. I did not use tarnish cleaner. I thought authentic I'd leave that to the buyer. The pouch is black leather. This has been carefully stored since 1945. Made in Hong Kong. Tag on the inside of pouch. The pouch is in very good condition. The mirror has some obvious wear. I have been the recipient of 3 generations of memories and I need to cut back. If you want more details, please ask. I took the best photos I could. Smoke-free home. Questions? Please ask!.
