I conducted a search of our database RecordSearch and found a listing for two records for Eric Alfred Leith Smith. There are digital copies of these records available, which can be viewed online. I will send you an email with the specific database information for the items as it is difficult to post it to the forum.
I also found listing for three records for Arthur Bennett Gossip, two of these records have not yet been digitised. Again, I will send you the database information by email.
I recommend you contact the Australian War Memorial as they may be able to better help you with photographs. Their contact details are:
