I was wondering if anyone here may have plans or a directly overhead photo of any Bird Class minesweeper (https://en.wikipedia.org/wiki/Bird-class_minesweeper), i.e. HMNZS's Moa, Kiwi & Tui ? I believe they were built for HMNZN by Henry Robb Ltd, a Scottish shipbuilding company (so I do not know if any other HM ships may have been built to the exact same design.)

Exactly what I am after is either;
1) Plans of any one of the three ships or of their Class (Bird Class),
OR
2) A 'plan view' (i.e. from directly overhead as it were) of any one of these three ships or ship Class,
OR
3) An aerial photo looking directly down, or almost directly, from above either of the three ships.

I already have photos of both ships and models of same from oblique angles, what I am specifically looking for is only direct overhead views, be it from a plan or photo.

I know it's a long shot finding same, but the reason I am trying to acquire said 'image' is to aid in research on the sinking of HMNZS Moa by bomb hits (in Tulagi harbour from a Japanese aerial attack during Operation I-GO on 7th April 1943).

TIA for any help.
