Wayne,I don't know anything about Musicground, being a yellow bellied southerner and all, but i would echo what has already been said and say hang on until something nice turns up on here. There was a real nice one on here in the for sale section (might still be there, haven't looked) for similar money, sburst & maple board.
I bought a 73 from Heartbreaker (refinished) for £1250. It is hands down the best bass i have ever played.
If there is some doubt about the retailer i would be mega worried when buying something "vintage".
all of this of course just IMHO!
