Hello Seaweed,  
The you for the help and advice about the national archives. also for the Plimsoll link.
I have just found a report about the Helmsman wreck on
 www.wrecksite.eu.
Thanks to ShaunJ's  address spot, Randolph St. I looked at the electoral registers a Richard and
Margaret Parry living at that address from 1923 until 1927. then just Margaret. 
Looks like I may have found my man.
Thank you all.  Eddie P.
