Starter Drive Pulley for Riley Air Conditioning System

[basloane]

I have a 1975 T337G with a Riley Air Conditioning system installed on the rear engine.

Recently, the inner surfaces ( the surfaces which have contact with the drive belt ) became damaged due to a cable rubbing, destroying the belt in the process.

I now need to replace this pulley and Belt.

The belt is a standard automotive type belt and is easy oto obtain, however finding a replacement pulley is the problem.

Does anybody have a spare, or know where I can obtain a new one?
