Here's your front brake handlebar lever assembly from Hitchccocks' web site, their part number AM/18/675
These are your brake cables as supplied with adjusters at the fork end, part number 38702 :
You can see from my photo how they fit, the adjusters just screw into a carrier, which is basically an extended stud for the mudguard stay, this, screwed into the lug on the lower fork leg. Part number 3837
The ferrules appear to be supplied with the lever kits. There's a ball-ended lever too assembly too, part no. 92731
