Horizontal pedestal dial for latitude 52° North. The dial has an octagonal bronze dial-plate with four screw holes. It has an hour-circle, within which is a minute-circle. The hour-lines radiate from a small circle around the base of the gnomon. The initials 'I * B' are engraved either side of the southern part of the meridian line. The gnomon is triangular with its vertical edge shaped into ogee curves (double S-shaped curves).

This dial, signed 'Elias Allin fecit 1606', was made during the time when Allen was still apprenticed to Charles Whitwell and is the earliest known example of his work. The initials (I.B.) are probably those of the original owner.
