Mechanical WW Benrus movement ID

[Watch2546]

I am just trying to identify this ,movement. I is a Benrus 10.5Ligne non-shock, sub-second and manual wind. It also has a regulator on the balance. Overall not well made, but I need some parts.

I have been through the old Bestfit catalogue and cannot find anything close. The set lever and yolk are quite distinctive.

Anyway if anyone has an idea that would be much appreciated.
