From reading Yeadon’s book on Raven, Thompson and Peppercorn Pacific’s, the tenders built in the series 700 to 782 appear to be standard non-corridor streamlined tenders, but with the low front. Those built at Doncaster had rivets and those at Darlington smooth surfaces. Apart from these appearance differences, were there any other changes from the earlier non-corridor streamlined tenders?
