''So he walked back with me. He walked in, took his darts out and straight away threw a 140 (two triple 20s and a double 20) and asked 'who set (the dartboard) up'. I said 'we did' and he said 'great, that's the correct measurements'.''
Mr Mustchin said Bristow, who died aged 60 of a heart attack, was a delight to be with and of the 16 players who took him on that July night only one managed to take a single leg off him in the best of three leg games.
''Like all cockneys he was very down to earth and called a spade a spade. I got to spend quite a bit of time with him then and got on really well with him. After he played (at the RSA) we went down to the old Portobello (Motor Inn) and we didn't leave until after 3am the next morning . . . he could certainly drink well too.''
He said he learned of Bristow's death about 6am Friday morning while he was watching a darts competition live on TV from overseas and the news came on.
Mr Mustchin said Northland's darting community would be in mourning over Bristow's death as the man was credited with making the game the international phenomenon it is today.
''It will be a massive funeral for him. Eric still went to most darts tournaments and was still throwing darts at a charity tournament last month. I was lucky to get a card signed by Eric too.''
When Bristow visited in 1997 the Northern Advocate interviewed him and commented that the rising popularity of the game then saw an international championship prize that year rise to $67,000. This year's world champion won the equivalent of around $800,000.
One of the sports first great players, Bristow was world champion five times between 1980-1986 and won five masters titles during a stellar career and received an MBE in 1989.
