That was my point.
Well, it's a very underwhelming (and incorrect) one. Though I'm too lazy to dig through the historical data, I'm willing to bet that its fall from the #1 spot predates the peak of manufacturing's share in the British economy. Also, most of the countries currently ahead of Britain in the rankings have a very high services/GDP ratio.
I'm also not sure why a tripling of British GDP per capita over the past 50 years counts as an "economic decline".

First of all, fifty years ago, Great Britian has already fallen from it's number one position in the world, so I'm not sure what relevance any increase over the past fifty years has to that point. What I'm talking about is "top dog" status: the number one economic powerhouse in the world. Right now it's us, but as we turn more to 'services' rather than 'manufacturing', we are beginning our slow slide from the top of the heap.
Secondly, I'm not saying that there is causation in the rixe of services vs. manufacturing in the decline of the top dog's relative strength. It could very well be an indicator rather than the cause.
Third, as for your bet, I would be more than happy to take it. Britian's share of the world's manufacturing production stood at 31.8% in 1870, and steadily shrunk until 1910 when it reached 14.7%. Britain still had it's financial services of course, and the pound still reigned supreme, but soon enough the dollar took over there as well.
