Pete - yes that is Belle - just before my daughter had her portrait made with her. The flames shot is slightly off focus - he kept moving to avoid the fire! (His name tag is nice and sharp at 100%, though

)
Brian - I first tested the lens on a 7s to ensure that focus was spot on and then the conversion was very straightforward, but tricky.
As I thought, if you have a properly calibrated lens, all that needs to be done is simply align and attach an LTM adapter.
I'll try to describe the steps I took later.
