RA Drives for EQ3, "I think"

[vespine]

I have a mount which I got through a very generous member of this website, I've been using it with limited success and meaning for a while to put an RA drive on it. I would like to try some longer exposure wide field photography. The only problem is I'm not 100% sure what I have or exactly what I need.

I think it is an EQ3, and I think this would work:

Can anyone say with any certainty if I am right?
Thanks.

It looks like it should, but I'd suggest contacting Steve Massey at Myastroshop and sending him a copy of the image.
