Great trivia piece, Andy: thanks. Six thousand, indeed? That’s quite a scary concept.
Think about it: if he wore each one for one day only it would take 16.5 years (give or take) to complete one rotation.
If they averaged ‘only’ $1000 each in value (not that we are interested in value, of course), there’s a lazy six mil. sitting on the metaphorical bedstand. If they were to average ‘only’ $3K each, the number gets uglier - you get the picture.
If half of them are on winders then (leaving aside the cost of the winders!) you’re looking at the thick end of a tonne of DD batteries a year at maybe $12-15K p.a. As for the other half, a full wind will take you roughly two full days to complete (by which time, with many of them, you and your bleeding fingers will be starting again…).
Service costs? Pick a number between two and five, add two zeroes, multiply by three then wait.
The most intriguing question, though: where on Earth does he keep all the boxes???
Cheers,
pplater.
