The following is the Oxfordstandard, taken from the publication 'The Old English Game Fowl` , by Herbert Atkinson- 5th edition.
Below is the standard of perfection as set out by the oxford club
STANDARD OF PERFECTION.
Head- Small, and taper, skin of face and throat flexible and loose. Note A:- A loose skin to the throat, to enable the cock to breathe freely when distressed in a long battle.
Beak-Big, boxing, crooked or hawk-like, pointed, strong at the setting on. Note B:- Boxing means the upper mandible shutting tightly and closing over the lower one, a long under beak lacks holding power.
Eyes- Large, bold, fiery and fearless.
Comb, wattles & earlobes- of fine texture, small & thin, in undubbed chickens & hens.
Neck-large boned, round, strong and of fair length. Neck hackle covering the shoulders.
Back- short, flat, broad at the shoulders, tapering to the tail.
Breast- broad, full, prominent, with large pectoral muscles, breast bone not deep or pointed. Note C:- An important point. Strong big pectoral muscles give the cock power to fly with strength & force, & furnishes the maximum amount of breast meat for the table.
Wings- large, long and powerful, with large strong quills, amply protecting the thighs. Note D:- Long and strong wings impart additional force to the blow when the cock strikes.
Tail- large, up & spread, main feathers & quills, large & strong. In the hen inclined to fan shape, and carried well up. Note E:- A high strong tail acts as a rudder, supports and balances the cock when striking , or springing backwards, and indicates courage, the first act of a coward is to lower his tail.
Belly- small & tight.
Thighs- short, round, & muscular, following the line of the body or slightly curved.
Legs- strong, clean-boned, sinewy, close scaled, not fat & gummy like other fowls. Not stiffly upright, or too wide apart, & having a good bend, or angle at the hock. Note F :- Legs, the bend of the hock, or rather the juncture of the metatarsal bone with the tibia, may be compared to the bent hocks & muscular thighs of the hare & kangaroo, in furnishing them with such wonderful propelling power. In cocks of this perfect conformation there is nothing wasted in these bones, which are constructed to enable him to move with force & velocity commensurate with their distance from the centre of the action, this is the reason the stork-legged bird has no force in his blow; & the cock with legs set wide apart and straight thigh bones is dry heeled, his blows do not wound or kill his adversary.
Feet- toes thin, long, straight and tapering, terminating in long, strong curved nails. Hind toe of good length and strength, extending backwards in almost a straight line.
Spurs- hard, fine, set low on leg.
Plumage- hard, sound, resilient, smooth, glassy and sufficient, without much fluff.
Carriage- Proud, defiant, sprightly, active on his feet, ready for any emergency. Alert, agile, quick in his movements.
InHand- clever, well balanced, hard, yet light fleshed, corky, mellow, and warm, with strong contraction of wings & thighs to the body.
