Hello and a few questions

[Sgt Shultz II]

Here is one dilema.

As I understand it the Mk I instrument panel has a black speedo and 2 guages on the inboard side.

The Mk II has the black and white speedo and 4 guages on the inboard side.

And then I find this which to my mind is a Mk I instrument panel with a Mk II speedo


I guess as always anything goes in war as far as replacement parts go. So when converting the Mk I to an Upgrade it would be a Mk I No. 2. Correct??

What original Mk I parts were deleted and what Mk II parts were added??
