My 1955 Lenton has nearly, if not identical bars... seems like these were in use for many decades and despite the lack of modern brakes and hoods they are very comfortable with those long flat ramps.
Spent my evening tweaking out my winter bike and installed an old fashioned headlight and with a fresh bulb it throws a decent amount of light at very low speed... will look at building up a battery pack to provide a stand light feature and keep me from over driving the bulb.
