Hello Roo,
I'm sorry for your loss, I also miss my Dad who has departed for the boatyard in the sky a while back !!
I have been researching and gathering information to build HMS Belfast for years as she is local to me as I live in Kent, whenever I'm in town for business I find myself aboard !!
I have the David Mc Gregor plans are for 1942 they are drawn @ 1/192nd scale which gives you a boat 38" long, I'm planning to scratch build her at 1/96 twice the drawn size, my wife recently asked me why I wanted to build her that big, that stumped me for a while 
Your welcome to paper prints of the plans + postage, If you personnel message me your address & email we can arrange something the prints will be around £12.00 for the 2 sheets.
Kind Regards
Ray
