Recoil pad fitting on old SxS (to grind to fit)

[Canuk]

Hi all,
looking to put a new Silver pad on one of my old guns (1915 Fox SxS). I guess there is a jig of sorts that you use to get the angles just right. e.g. Wheeler Fixture. but I dont have one.

I'm thinking i'm probably best getting someone who has experience to do this for me.
Does anyone have any advice on who I might contact to help me with this.

I currently have a vintage Winchester model 12 at Corlanes getting a recoil pad installed. They have videos on YouTube of such tasks which reveals good work. That made my decision to send it their way.

Had 3 put on last year at CSC in Cgy. Two rifles and one shotgun, also installed a Deltapoint sight on a SXS rifle for me.
