Graham,
This is one of two bowling publications that was around in the 1960's. The ATBC - when it existed and was at Brookvale [and pre that at Chatswood] - owned a sizable collection of bowling history all catalogued and in public view [well largely in view - the size of the collection was impressive and this made it hard to exhibit in total in the space available at Brookvale]. Bob Partidge was very particular about ensuring the history of the sport was maintained - as were many other bowling officials at and before the middle of the 1990's.
It appears that since then however the emphasis on maintaining the history may have subsided somewhat, although I can't be sure what the status is now. I know some individuals have tried to do what they can - although frankly, I have no idea if the current administration of the sport still has the collection in part or in full at this date.
It might be worth asking - who do you ask by the way?
