Couplings for brandbright quarrymans coach

[Colinjamesporter]

Hi,
Happy new year.
Im currently building a brandbright quarrymans coach kit and have nearly finished it. I was wondering if anyone knew of any company thar does the correct pattern buffer and hook set up.? I looked at the slaters ashbury coach and djb bugbox couplings but these are a different pattern.
Thanks in advance.
Best wishes
Colin
