I am looking for help at British Bofors 40mm

[Zbyszko Kruszona]

Hello,
I'm rebuilding platform Mk II for Bofors. Some parts are missing and part is cut out. I have a problem with the extension girders (I do not have them).
Please help. Maybe someone knows or has a picture of the handle on the frame. I am looking for dimensions of this part and gun stay for my version.
I think that this is an early version of the Mk II platform, but I'm not sure.
I found one picture in the internet with such a handle but very blurred.
Thank you very much for help.
Best regards
Zbyszko
P.S. Maybe someone has extension girders for sale or dimensions?

These are the same areas on mine, nothing missing there. I'm not sure I understand exactly what it is you need.

I can do you a drawing of the extension legs.

These are the arm support brackets that been cut off yours. The pictures are of the same trailer that you posted earlier which is part way through a restoration in New Zealand. Like you... extension arms and levelling jacks are missing.
