Pardus SL chokes

These are god damn impossible to find on this planet it seems. A few months ago Gun City were selling a Pardus SL semi auto shotgun as faulty on trademe and it was at 140 bucks with two minutes left so I thought screw it and got it, turns out there was absolutely nothing wrong with it. Only thing wrong really was it didn't come with the choke set you get when you buy it brand new and I cannot find them anywhere.

Does anyone happen to have a set I can buy off you or have any knowledge on compatability with other brands of chokes? There is so little information out there for this shotgun.
