Glad to hear he's OK Michael.
I look forward to seeing your dad's collection on here as I know he had a few really nice guns.
I hardly ever use the 54 as it's a bit too good for what I wanted it for, but by shear coincidence I bought a 52 from the man who's post on fume bluing inspired me to have a go after my chat with your dad.
I suppose your dad will be keeping his favourite Diana underlever ?
All the best Mick
