Thanks very much for all your replies.
No mounting holes have been filled.
The front of Ron's guard in the picture does look the same as my guard apart from the position of the front mounting holes.
At least it will not look too out of place on my 16h.

red hunter or something, front stay holes are on the sides like yours. :)

Thanks Barry that seems to narrow it down further.
Cheers, Nick
