Redferns Ebonite Low Loss Coil Quoits. Manufactured by Redferns Rubber Works Ltd, Hyde, Cheshire.

A typical component for the home constructor from the mid 1920's.  This ebonite former is used to create a coil by winding thin wire around it. The quoits can be ganged up by slotting several together.  These coils could then be used as radio (circuit) tuning devices.  Approximately 5.5cm x 6.5cm x 2cm (w x h x d).  The former is 4cm (inner) and 6.5 cm (outer) diameter.
