Subject: [CR]What type of lamp/light for fork mount on 1950's Jack Taylor?

Can someone offer suggestions as to what type of lamp or light would have been used on a 1950's British road bike with a drive side,fork mounted lamp bracket?Recently picked up 1959 Jack Taylor Clubman #3352 (thanks Mick),and I would like to kit it out with the correct lamp. This model also has what appears to be the original headset,which seems to require some sort of pin spanner to engage a pair of holes on opposite sides of the top nut and upper adjustable cup.Might there be a way to adjust these without using a rare and elusive special tool?
TIA...
