I think he may also be locationally challenged - this same instrument is on Gumtree in Bournemouth, Brighto (sic), London and Belfast, and is also listed in Birminghan (sic) as a saxaphone.
Bit worrying about teh white gloves - do you think they're wedged firmly in the bell? Or maybe the seller found a use for them - washing the dishes, maybe.
Not only does the seller not know where they come from but their maths is not much better either the Birmingham listing is for £3400
I would go for the Yamaha ATO in west midlands
It might be a bargain if you can try before you buy, but it looks a bit overposted all around the country.
