Need to identify multi port valve handle

[RayGill]

My handle/lever on my multi port filter is broken.
There is no manufacturers name or number on the filter or handle.
Can anyone help identify the part?
The filter is stuck in the "filter " position and I am unable to clean the pool via waste,backwash etc.
I am trying to send a picture but am having problems.

I forgot to add my pool is in Cannes , South of France, about 30ft x 14ft x 5ft.
If anyone has a tip for cleaning the bottom of the pool until I get the filter sorted it would be appreciated
Many thanks in anticipation.
Ray.
