The John Litster record of pre-war players has Davie signing for Celtic on 05/02/1905 and then again on 21/04/1907.
Davie was born on 13th December 1890 (Alphabet of Celts) and would therefore have been 14 years old when he first signed and 16 years old in April 1907.
Were players able to sign for a club whilst under 18 years old in those days?
