Old English Game Bantam - Comb

Is it a defect when showing Old English Game Bantams to have a rooster with a Mulberry coloured comb, instead of Red.

Is it a serious defect if the Rooster has a Large Semi Erect (single) comb?

Can't find any information on this.

I assume that standards for the comb would be similar in most countries.

Would really help if someone had an answer.
