Thanks Scouse, I found that info. On his Navy Record it says ' Borda Australia ( with a number above, 135340) AB 2-6-20 Vic Dks. I read that as, he sailed out on the Borda on that date and went to Sydney. The Borda did dock in Sydney in Aug 1920 a few weeks before the Amelia J set sail. I think the Borda was used as a troop ship and went back into normal service around that time. This record is on his RNR page. Could he have been hired to deliver the ship back to Australia?
This two page record I have list his RNR service and his WW1 service. I cannot read the headings very well, just some of the hand written stuff. Do you know where I could get a look at a clear record form?
