Based on a combination of recipes, including Graham Wheeler's BYOGBB, and some posts that indicate the original ingredients are:
93% pale malt
4% crystal malt (use Bairds British Crystal Malt 135/165L and Briess Blackprinz to reduce astringency)
3% cane sugar
The bitterness units of 22-24 are obtained from Fuggles hops (85% of total) in the copper and Goldings hops (15%) on the hop back plates.
