A very fine example of this much debated, Dingleyesque, reel.
Personally I don’t believe it was made in Alnwick but most likely in Scotland.
This reel has a caged spool with telephone latch; wraparound brass foot, ivory (?) handle and caliper check. The (reversible) check has the click on the retrieve and silent out – see photos.
Badged oval for Robert Turnbull, Maker, Edinburgh and neatly engraved owner’s name “J. A. McMaster”
