J.B is correct, the trigger is a very simple design. If you've done a mkII you can handle this one becasue the sear is almost identical and that is where the most material needs to be removed. I took about .015" material from the sear and ended up with .021" engagement. Make sure you use the appropriate tool to measure the depth of the sear engagement area (depth gauge works pretty good). One guy says he had to do alot of work to get his hawkeye to shoot 1 1/2 inch groups. Mine shot this well out of the box with cheap a$$$ ammo. I shot some 1 inch groups the other day with some handloads before I worked my trigger over. Can't wait to take it out now and try it.
Sorry, guys, I don't have any photos. But the trigger is so simple (anbd comes apart so easily) that if you've done any trigger work at all, what needs to be done is fairly obvious. Mostly it's a matter of honing the engagement surfaces.
