A good run of antique solid cast brass sash window locks. Heavy and solidly made with evidence of past life abundant. Spring still springy and nothing bent or missing. In full working order and suitable for sashes with a combined thickness of 6.5cm or greater. Catch mounting plate 2.5cm wide, keep mounting plate 3cm wide. These items are polished to order so a delay of 48 hours to our usual posting time should be expected.
