Antique flintlock pistols are restricted for firing, but they do not require a permit to purchase, an "H" class licence or registration. So if you can afford to purchase one, you will have a good back up handgun should you ever need one in the future. Not all are expensive, there was one recently in an auction going for a very reasonable price, had I been able to justify buying another one, I would have got it. Mixed parts antique flintlocks are less expensive because they are just that, a pistol made up of various antique parts. The same as damaged flintlock pistols, broken stocks which can be repaired, a steel/hammer or cock that can be replaced. A missing trigger guard. Worth keeping your eyes open. www.australianarmsauctions.com/ Keith.
