Cycling UK Forum

Can anyone please help. I am trying to identify which model of Moulton this is, on behalf of the daughter of a fellow cycling enthusiast friend, who has sadly died.
Any info on which Moulton model and approx date would be much appreciated, in order that we can gauge a fair sell price, as she intends to sell it.
I have looked at Moulton's website and am confused by the variety of types and models.
The number on the B/B is 426031.
Thanks for any help.
