I did. *Oops!

The stock earmarked for the Island Line is either 1972 or 1973 stock.
The 1972 stock is almost identical to 1967 stock but has manual diving
controls.

But when with the 72/73 stock be replaced? *I thought that they were
up for replacement around 2015, and surely by that time the IoW fleet
will be falling to bits. *With the ex-Victoria vehicles becoming
available somewhat sooner, I'd have thought that they would be used.

Sorry, I am just repeating what I have heard and read. *I don't know
the reasoning behind it, but perhaps the cost of installing manual
controls and the extra age of the 1967 stock count against it?

Some of the 1972 stock was actually built as late as 1979, so perhaps
those are the vehicles that have been selected? *That would make them
a decade younger than even the last produced 1967 stock.

It definitely wasn't. It was transferred to the Jubilee in 1979 but
only after running on the Northern and Bakerloo for years.
