k4774 Sunderland Prototype Step Question

[sunderlandmr5]

Hi All

The 1937 Prototype had the straight wing, and as I have discovered a step foward of the "newer"
repositioned step on the updated prototype (swept wing, step further aft etc)and production Mk I.

Question is, does anyone know where the original step was, or have the distance of the 'Initial"
Prototype step (ie distance from nose to step).

I have looked through my books etc but cant find anything to indicate the original step position.

Thanks

Alan

Curious isn't it that none of the books say how far - just quote 'moved the corresponding distance'.

It was because the centre of gravity was moved by installing the tail turret and both the wings and step needed moving back - in the case of the wings by sweeping back. I've had a plough through my files but I can't find the right documents about that change. They must be there somewhere but I just can't trace it at the moment.

However, in my photos I found these two - have a look at the position of the step relative to the beaching gear and the bomb bay doors.





And here, for fun - well it must be Christmas in NZ by now - is the step on K4774 later when they were testing the fairing for the MkIII. You can still see the join.
