I like singleshot break actions. I found another brand that will work to make heavy barrel 12 and 20 ga FH. By monoblocking in heavy barrels. It is the CBC Model SB. It has stock mounted like more expensive doubles and O/U. And nice shaped pistol grip stock. They have the nice stylish look like the Win 37 and Stevens 94. But they are heavier built, just need heavy barrel. I going to do a couple by monoblocking in heavy barrels, one 20ga and one my 585 HE like I did in the NEF.And they are 50 to 100 bucks.
That action is a 1/8 inch wider than NEF, has big breach diameter like NEF 10/12 gauges. The bearing surfaces on the pivot is .300" wider, and pivot block is 1/4" wider. Pivot pin is 1/10" bigger. The action is a 1/2 inch taller, and extra diameter at breach end. In fact you could build a real hairy 8ga on its wider action, with a heavy barrel and a new pivot block welded on.Ed
