I used to hear a lot about JJ back when I was going on safaris years ago; haven't thought about him in a while. My double rifle is also a sidelock. As you mentioned, he's really highly regarded with them. He does retail and repair, right?
I've had good conversations with two of the guys mentioned previously; leaning towards the one that said he should be able to get the gun good to in a month as compared to six. As you might imagine, having this all wrapped up before the fall has appeal.
