Thanks David
I am pretty sure that the lens is centred but I will check that the gate is full height and get it modified if not.
I realise that there is no particularly useful point in watching something shot with a Cameflex but I waited my whole life to get it so I feel rather attached to it in a sentmental way and it will be a little while before I get to shoot anything with it myself.
I will post back with news and hopefully useful info as soon as I have progressed further.
