The bike isn't shown on the seller's website currently. It looks to be the same one offered on Ebay c. 6 months ago - non-matching numbers and a very high asking price that no one offered to pay.
That listing claimed the bike was restored by Mike White in 2003, again by the Harris Vincent Gallery in 2004, again by Mark Allen in 2012 and was then refreshed by Harris Vincent Gallery in 2017 and 2020. Of course it needed all this work, the last two rounds costing $20,000, since it had been ridden a total of 105 miles during the past 17 years.
Some Vincents are apparently high-maintenance...
