Hi Alanv, I have a totally original Bown 1953 98cc. I have compared head lights with 1952 Excelsior Consort, its very similar, so you would get away with one of these until you found an original one, nobody would know. The only originals I know of is burried in the old Bown Llwynypia, works in Wales. If you have any problems let me know and I might be able to help you out. Do you know of anyone else with a Bown. If you get a chance email pic of your Bown, I will send one of mine when I get it digi photo'd.
Jim
