Thanks chaps. Lots more than I thought but I'm guessing not every law abiding Scotman who needs one has one.

If someone remembers or finds their old rifle in the garage and take it to the local station I hope they won't get arrested.

I can't find anywhere what the sentencing is for the crime of possession? In England and Wales possession of an FAC rated rifle is I think 5 years and £5k fine? Or is that just armed trespass?
