What you need help with?

Taking the internals out of the bottom picture and putting them in the top

I've already re blued the top, I know it's not wise to do so while its intact but I oiled it down after the blue was put on. So if I'm lucky I just need help replacing the trigger and trigger guard.

Yeah not much to it. Phillips head screw drivers of the appropriate (near, under) make good slave drivers for getting the pins out. I grind off the heads of the drivers. Cut a short piece of round stock out (out of anything) that will find within the holes of the trigger guard and within the confines of the outside width of the guard. Just feed it through the various parts and stick it in the receiver. Use your punches to knock the pins in. As the pins go in, the parts will pass from the slave pin the master and life is good. Nothing to it.
