These are so rare that it's extremely difficult to value. They are superb guitars - I have been searching for one for over 20 years now (I own a Gordy 1710, its predecessor, of which only three were made). But that pink clouds finish is an ... ahem, acquired taste ... unfortunately, it would be a deal-breaker for me.
A bit of info on them, for anyone interested. They were hand-built in Manchester, UK by Gordon Whitham, one of the founders of Gordon-Smith guitars, after he moved on. They have neck-through construction, similar to a Jackson Soloist, with Gordy-designed tremolo and pickups, Sperzel locking tuners. I don't know about the woods. They're as well-built as anything you'll find.
The late Pete Haycock, of ELO Part 2, played a Gordy 1840 (an embellished version of the 1810) to great effect. https://www.elobeatlesforever.com/2015/02/pete-haycocks-elo-guitar-legacy.html
