U.S.STANDARDS
In the U.S. nitrate of any form is no longer permitted in any bacon curing method, the concern being with the formation of nitrosamines. Sodium nitrite (E250) is allowed at a maximum ingoing amount of 200 ppm and Potassium Nitrite (E249) at a maximum ingoing amount of 246 ppm (these figures are for bacon cured with the rind off). If the rind is left on then these figures must be reduced by 10 %.
U.K./E.U. STANDARDS
In the U.K. cured bacon may have a 175 mg/kg (or 175 ppm) residual amount of Sodium nitrite (E250) or Potassium nitrite (E249). This being the residual amount at point of sale to the final consumer, expressed as Sodium Nitrite (NaNO2). There is no given Indicative figure given.
As an ingoing/indicative amount of 200 mg/kg (200 ppm) Sodium nitrite will reduce down to below 175 mg/kg (175 ppm) then also for 100 pounds (45.359 kg) of meat you could use the following cure mixture.
3.488 kg (7 lbs 11 oz) Salt (76.744 %)
907 g (2 lb) Sugar (19.956 %)
150 g (5.25 oz) Cure #1 (3.300 %)
Total Cure weight 4.545 kg (100 %)
Use the above cure mixture at a rate of 100 g per kilogram of meat; therefore if you are going to cure a piece weighing 10 lbs (4.5359 kg) divide everything by 10
350 g (≈ 12 � oz) Salt (76.744 %)
90 g (≈ 3 ⅛ oz) Sugar (19.956 %)
15 g (≈ � oz) Cure #1 (3.300 %)
Total Cure weight 455 g (100 %)
Again use at a rate of 100 g cure mixture per kilogram of meat.
I hope that this answers your questions

FYI you wrote
I have a magazine which has an article in it by Maynard Davies about dry curing bacon/ham in a plastic bag.
Technically this is not dry cured.
