I bought it from Mr. Baker’s eBay store. He had several nice ones. I am fitting a 1720 to it. Currently sanding the slot wider to fit the trigger group. Then the big deal will be to cut a hole for the gauge. I think the will be in the “Critical cut” category that my smart son says I am forbidden to do. I will go to his house for that. Or I need to go and buy a drill press.
