I thank the responses so far.
Most of my work involves as a poster in another part of this site calls "shiny wood" but I've done my share and been witness to parts of this required detail in a variety of carbon and stainless steels.
My plan was to first create a drawing with all the details primarily for my first op.
If I go the replace route I will start with a laser cut blank as the one detail, what I'll describe as the pivot point (right pic upper left corner)just looks like a pita evan with a cnc.
The rest of the work I believe I can accomplish with patience.(and possibly the 2nd or 3rd laser blank)
This will not be a money maker, a bit of a personal challenge and for someone who has done me many a favor without asking for payment..
I hadn't really considered repair until brazing was mentioned above.
I have experience with tig brazing.
These are pics of the part as given to me.
Is it possible the manufacturer cast this part, the break looks like a casting fracture, not a tear I would expect from a wrought material ?
I also have the mechanism it needs to fit in.
Although I don't know the mechanics of operation I was shown what the locking block should do when fitted.
