additional photo for my Janita valve grinder question

This photo file was too large to attach to my question re. Janita valve grinder dated yesterday - am therefore posting separately.

Hi Pip, I've just seen your post and can confirm that it is a Janita valve grinder. i have just got one myself and I'm in the process of re-wiring it and giving it a general strip clean and re-assembly. I'm struggling to get the central wheel screw undone. I'm assuming it is left-hand thread but don't know for sure. Do you have any idea?

thanks
Andy
