Hi Listers I am researching the Street Family of Derby,I know they were boat builders late 1700 and 1800. Their yard was In Exeter Street Derby. I have received some info on the boats they built being O.T.gauge,I have no Idea to what this means. I assume It Is something to do with the size of the vessels,can someone enlighten me please!!
