Finally riding a big boys bike
Vintage handlebar mounted sealed beam spotlight with a glass GE bulb and Delta chrome bracket. It is connected with an insulated wire to a Delta rocket-shaped 6 volt lantern battery holder with built-in brackets on the bottom for mounting to your frame. All original paint. I don't have one of those batteries so I can't test it but my guess is that it would easily work since this is pretty basic technology. Free shipping in California, all other states add $15.
