Vintage gold filled ALGHA shops reading glasses

Product Name: Vintage gold filled ALGHA shops reading glasses
Vintage ALGHA reading frames Gold Filled. Made in England. Don't know if they are 20 karat or not. I'm assuming they are gold filled because I paid a lot for them around 1985. There is a “20” in a circle next to the logo on the inside of the bridge. Maybe that's just the style number? Very mild reading lenses. Frames in excellent shape, might need to be tightened. I haven't worn them for over 30 years. Exactly 5” wide. Temples are 4” long. In an old black hard case. The item specifics shops are too complicated for me so I tried to be accurate in the description here. Mercari doesn't list the brand name in their listings of over 5 gazillion brand names!.
