It's only an estimate and it may go higher of course, also the reserve may be set above the estimate. The 16.2% commission will add considerably to the hammer price !
Presumably there was no interest when advertised by this Morgan dealer. Surely if they'd listed it at £40k rather than £60k it would be sold which makes the auction estimate look a bit peculiar.
