You're looking for something extremely specific there. Not many were made, even fewer will be up for trade or sale.
Have you considered trying to contact Jackson Robinson for help? I'd never discourage you from advertising here, but you're looking for a specific needle in a field of haystacks, with no magnets in sight.
Actually I missed 1 line... I don't mind it even if it is not no 47
but I of course my preference will be no 47
You're still looking for a very rare item. The rarer the item, the lower the odds of finding one on the market.
I'd still talk to Jackson, were I in your shoes. He might help make the search easier. Worst that could happen is he says he can't help, in which case you're no worse off than you are now. Best that could happen is he helps you broker a deal with a known owner of the deck, maybe even the owner of #47.
