Hard to beat free...I'd get a professional to do any work I had done on it. (forget your local gunsmith and lock up your welder)

The 12 magnum 3" "eclipsed" the 10 ga. here in the states but I didn't think the 3" 12 was that popular over there....In all my searching it's kind of a rarity to see a 3" magnum English 12 ga.

I'm finding it hard to believe that a 10 ga. is rarer than an 8 ga. in England...the prices that even the low quality 8's bring doesn't follow this line of thinking.
