Thanks of thinking of me, JDW, but I have very little experience repairing broken stocks.
That said, I am not as big a fan of epoxy, acraglass or super glue as some.
I prefer Titebond for installing ebony forend tips and othe major wood to wood adhesion. And Duco Cement for lesser stock repairs and checkering fixes. Either will take stain and will not show a shiny glue line.
