Perhaps some more recent Tube stock could be purchased instead? The

with the long established tradition of using secondhand stock from the
mainland.

Isn't the problem with older tube stock, including the 1967/72 TS, that it
isn't alloy enough? In other words the combination of aluminium bodies on
steel underframes is the real corrosion headache on Ryde Pier?

Quite possibly.

How much of an issue is corrosion on the Island Line? Are they really on the
pier for long enough periods of time that it can become problematic?
