Part A
Water 125F/52C750ml
Metol8g
Sodium Sulfite (anhydrous)23g
Sodium Carbonate (monohydrate*)23.4g
Potassium Bromide1.1g
Cold water to make1000ml
Part B
Water 125F/52C1000ml
Sodium Sulfite (anhydrous)23g
Sodium Carbonate (monohydrate*)63g
Hydroquinone8g
Potassium Bromide4.4g
Cold water to make1000ml
Mixing Instructions: Add chemicals in specified sequence.
Dilution: #1: 8+0+8, #2: 7+1+8, #3: 6+2+8, #4: 5+3+8, #5: 4+4+8, #6: 3+5+8, #7: 2+14+0
Usage: 

Notes 

*multiply amount by 0.833 if using Sodium Carbonate in anhydrous form.

Contrast is controlled by mixing A+B+Water. #1 is the lowest contrast and #7 is the highest contrast.

To make working solution divide the final volume of developer required by 16, then multiply this number by the corresponding value in the required dilution. eg. To make 2L of working solution: 2000ml/16 = 125, then multiply 125 by the number listed for the particular Beers number (contrast) that you require. eg. for Beer's #6 multiply 125 X 3 = 375ml of Part A 125 X 5 = 625ml of Part B 125 X 8 = 1000ml making a total volume of 2L.
