Brass on gold plated glass

Found this neat clock mechanism in great uncles basement trove of ancient goodies. The glass was harvested from a lighthouse beacon. I am not sure what the clock was used for, it came in a small brass container, the clock only has a winder, no provision for mechanical connection to hands, it's very old. The glass is neat as it's been gold plated on both sides and seems to filter out all but blue light.
Again just fooling around, it's a good cure for 3 am insomnia.
Tried the 18-135 for a change, not a bad image for a zoom.
