In relation to Condition Reports, whilst we make certain observations on the lot, which are intended to be as helpful as possible, references in the condition report to damage or restoration are for guidance. The absence of such a reference does not imply that an item is free from defects or restoration, nor does a reference to particular defects imply the absence of any others. The condition report is an expression of opinion only and must not be treated as a statement of fact. Measurements and weight are approximate and the potential bidder may re-ask it to be checked when asking for a condition report.
