A mate had some fitted to a 750F2 originally and still has both the shocks and box.
They are as Oddjob rightly recalls labelled as AG STRADA (good memory oddjob).
The part no info on the end of box is as follows;-
Art. 87.317
HONDA 1000
M.91.31
AG ST
The casting and assembly looks the same as your photos, with the reservoir to be mounted on the bottom swingarm fixing and not upside down.
