A 19th century ships clock by C.C. Webb, 1 Royal Exchange, London, with silvered dial and single fusee movement housed in an oak case, total diameter 24.5 cm, and a later aneroid barometer by the same maker, total diameter 29 cm (see illustration). CONDITION REPORT: The movement winds smoothly and appears to be ticking away as it should. The brass bezel has lost much of its original lacquer. The glass itself is in good condition. The lever for opening the door is a later replacement and not very effective. The silvered brass dial is tarnished and marked in places. The outer frame looks to be later than the clock. The outer frame will be circa 1900. It is in generally good condition with only minor scuffs and marks as one would expect. The bottom of the case underneath the numeral 6 is veneered and the veneer is slightly lifting. When you remove the backplate from the clock all you can see is the rear brass movement plate and the escapement. It is not possible to see the movement at all. The barometer case is in similar condition to that of the clock. There are some minor edge nibbles and the outer case is a little dirty. The brass circumference is tarnished in places. The silvered dial is a little yellowed. We are not sure if the barometer is actually operating.
