It's a lamp bracket, designed to fit one of the old Ever Ready lamps.
The lamps ran on two D sized batteries which lasted for an hour if you were lucky, and illuminated a small patch of road about 6 feet in front of you. The spring loaded clamp on the lamp wasn't great either, so on occasion if you hit a bump the lamp would spring off your bike and clatter into the road, popping apart, shedding the batteries and frequently breaking the bulb too.
There was a rear version too, which had a bolt on clamp around the seatstay. Same battery life, just as dim, but at least it didn't ping off the bike.
Brings back memories of evening rides in the 80s - we rode in a line with the leader being the guy with a working front light and the man at the back having a working tail lamp. Happy days, but I love the rechargeable LED lights I use now!
