Albert George Ervine Assistant Electrician

[Darren Owen Ervine]

My Great Uncle (Albert George Ervine) was an Assistant Electrician and wrote a letter to his mother (as referenced on this webpage https://www.encyclopedia-titanica.org/bio/c/e/ervine_ag.shtml)
Anybody know how I can get a copy of the original or where it would be found?
Thanks and appreciate any help!
