The Elizabeth H.Fletcher was launched on 03-09-1958 for a Dutch owner as TORONTO,and was build by J.Boot "De Dageraad",Woubrugge.In 1962 she became Elizabeth H.Fletcher.
The right names of the others are:
Yardnumbers:1283-1284 & 1285
They all had a 4stroke single acting 8cil Industrie engine.
Measures: 134'10" - 24'11" - 10'7"
This is all I found and hope its helpfull.
I just found a picture of the Toronto on:www.scheveningen-haven.nl/info/ijmuiden/index.htm
