Hi Mick.
I really must learn to say no when folk try to talk me into things.
I'd have to lop the barrel off to get it in the freezer, so not really an option.
Its had 24 hours soaking in plus gas and I've scared the bloody life out of it with a mallet. It refuses to budge.
If it were mine, I'd get it apart somehow and if necessary refinish the alloy block, but I'm loathe to go to those lengths on something that isn't mine.
Just had a chat with the owner and its of sentimental value, so it may just get put away for another 30 years or so.
Rob
