I'm not sure what you mean about the bitch not being registered because 'it had gone over the time allowed' - adult dogs can be registered, but only by their breeder. It costs significantly more than registering a puppy though. Did your friend breed the bitch? If so, why didn't she register her? If your friend wasn't the breeder, she must have realised that the bitch wasn't registered, and would have asked the reason why not. There's usually a very good reason - the litter the bitch was in was from an over- or under-age bitch, or the granddam's registration was endorsed.
There's no point in using any registry other than the KC because they are meaningless - you could just as well print out some registration forms yourself and save lining anyone else's pockets. The papers would still be worthless, but so would any others you bought that weren't issued by the Kennel Club.
Your friend will just have to sell the puppies as unregistered.
