Hi Col,
Sorry to take so long getting back to you.
I've attached what I have so far. The holes may need to be reamed out slightly
and The handle is still oversized by about 10mm width.
Life keeps getting in the way

Hopefully one or two more sessions and it will look much prettier.
I haven't tried to offset the handle as
a) I don't want to bend it to close and too much.
b) it will be a bugger to bend (1/8"steel)
Cheers,
