Hi, I don't have any information about why that ship was going to Rangoon. But thought you might use this information.
By no means am I an expert...I just search the net.
Hull number is 526
I believe it was called the Ethiopia Victory
Ship number is VC2-S-AP3/AK 281 Victoria
I got this information from the site below. You may be able to contact them and get some history and a picture. There is a cost involved though.
