This is a superb and rare example of an early French graphometer signed “Butterfield à Paris” with a spectacular strawberry decoration with four strawberries and very elegant plants and acanthus.
The graphometer is from the early Butterfield production, circa 1680.
On the center of the graphometer a large and finely engraved compass with its original magnetized needle.
Otherwise, the half-circle is divided from 0° to 180° and 180° to 0°.
The back is quite unusual with no place for a ball-joint and a stand ; futhermore, there is no place in the case for the stand. This is certainly an early configuration.
The fine brass graphometer is preserved in its original shaped travelling case on one sided fully stamped with fleur-de-lyse.
A little lack of leather at the case otherwise excellent original condition for this excellent French graphometer for the best production from Butterfield.
Size is 20,7x11cm (14,3cm height witht the ring) and the case 22,5×13,5cm
