The outer faces of the stretch links on this 1961 7912 look fine (5 one side, 3 the other), but the inner faces looks like the stretch links are missing the sliding plate seen on later 7912's and 1039's etc. Where the stretch link spring has broken I have seen some stretch links where the sliding plate has been removed and the link compressed with pliers to close it as a bodged repair; however, this results in an ugly looking link which is much skinnier than normal (not the case here). You can see that the stretch links are present i.e. they have not all been replaced by regular non-stretch links. Does this look like a transitional 7912 with non-serviceable stretch link springs?
Any help appreciated!
