Excelsior Consort. 1951 handchange

[Don Vosper]

Hi,
Just got this bike running so hope to get it through the MoT soon with a bit of work.
I'm looking for the following spares to replace some non-original parts if anyone has them.
Steering head nut:
Handlebar clamps:
Brake pedal:
Chain tensioners that slot into the rear forks:
Cheers
Don.
