Hi Alan,
I don't think I found my g/g/granddad's ticket in FindMyPast as I have only in the last couple of years, occasionally subscribed to it.
I might have found it in the CLIP website (Crew List Index Project).
http://www.crewlist.org.uk/index.htmlI find it a difficult site to navigate and to understand some of the info I obtain.
BUT, you can find out many things on the merchant navy.
This is info on the ships named GEELONG along with their official number.
