long shot

This is a long shot for the more mature drivers amongst us.
I used to have a good mate who i worked with at william nuttalls of clifton m/c between 1969/74.We lost touch when i left,his name was duggie williams and he was a big lad about 18st and always wore a bus drivers hat.He lived in bolton at the time and was about 28yrs old,i did hear that he emigrated to the usa but this was only rumoured on the grapevine and i have ,never ,found any real truth of this.Im clutching at straws i know but if anybody out there has any info at all i would be most grateful.

Thanks Regards Dave.
