hiya savo sorry cant help you with info on your prefabs,it has however reminded me of the ones on Croft street off Prescot street ,i think Ged has a pic on his site. I also remember them being on the opposite side of Prescot street at the end of Hardwick street just before St Judes Church....early to mid sixties which was roughly facing the Old Fort Pub.{The Pub still stands today] ....as kids.we used to call them the matchbox houses.
...good luck with your search !
