I have five 1894's and have taken all of them apart a number of times and that part still gets me sometimes. You'll sometimes fiddle around getting the safety in the right position so the trigger plate goes down on the receiver only to find that part has rotated to the wrong position. The only problem, or part to watch when re assembling is the part between the sears with a tapped hole for the trigger plate to screw into. He's completely restored a Parker or two and three Remingtons for me and I've always been happy. He knows what the case colors should look like for all the American doubles, each are different. Brad Bachelder in Grand Rapids Michigan does excellent case colors and cold bluing or re doing Damascus barrels. If your gunsmith wants to hot blue it, find a new gunsmith who knows what he's talking about. No Remington SxS was plated and none were hot blued.
