...particularly when you're incorrect - on both counts - David:

1) The turret-sides are sloped - not straight up-and down (see bottom pic):

With these slopes being yet further straightened/enhanced, in the latest-worked versions.

- and -

2) I just showed an example of turrets with "bumps" on the sides - of both forward mounts - on HMAS Australia:

As also found on the vast majority of the historical reference pics - as well as all drawings - of this turret, that I have collected. The "bumps", appearing in almost all the above to have different lengths, were very likely some type(s) of sighting periscopes: retractable in various degrees - even to flush with the turret-sides.

In any case - whatever they were - this is the kind of detail I am always going to include on a master: very easily just shaved off of any casting(s) where not desired (as, in fact, appears would be the case for Exeter herself).

David, you would do a lot better by asking about such items before just laying down conclusions, as you did above (which, among "normal people", is also distinctly rude), buddy.


Cheers,
