A pack of four McKenzie & Holland single ring brackets, as used by the Hull & Barnsley and London, Brighton & South Coast Railway companies. These brackets were normally used with the trimmers and crosstreads in S008/6 and S008/7 - check with photographs of your chosen prototype before ordering.

The brackets are 10mm (2'6") wide x 11.5mm (2'10½") deep - the larger "triangle" goes adjacent to the base post.
