Hello geraint , it is probably S J Morris from Llanfechain your father can remember , they backloaded tinplate from Gwynn Bowen as indeed did Trevor Morris , both firms are related S J stood for Sarah Jane the mother of Trevor Morris .
SJ Morris hauled most of the tinplate to Heinz at Kitt green , most of the Oswestry hauliers did along those from the Shotton area , SJ also did timber and livestock ,but now have just a couple of wagons now . Yes your father was right , they and Trevors fleet were immaculate , perhaps your father can remember Direct Transport at Gobowen another smart little fleet ran by Dennis Charles , i can remember BC haulge , but they finished years ago , in and out of Shotton they had AEC Mandators , thank you Trevor .
