Talking Engine Couplings?

Hi Guys,

I don't know if anyone out there can help, but I just obtained in an auction a talking Percy, price was quite reasonable, but when it's arrived I found it has a broken coupling which wasn't mentioned. It could have happened in transit I suppose, but I've naturally gone back to the seller anyway as it wasn't mentioned in the listing. But frankly I'd rather fix it than return it as I'm sure I'd be unlikely to get another in generally good condition for the price I paid.

Anyway as you probably know the coupling isn't the standard type otherwise it would be no issue. But I don't have any spare ones of this type, does anyone know where I could get one or happen to have one in a spares box I could purchase off you?

Here's a pic showing the broken coupling;
