Sorry for the late reply, just came across this post. I can tell you a little more about the stock, but not sure about who fitted it to the barreled action.
The stock is, or resembles exactly a Hans Adlhoch laminate stock. Hans lived in Victoria, was a cabinet maker as far as I recall and shot small Bore for Canada in the 1976 Olympic Games as well as multiple other world level events. I met Hans when I started back into Full Bore shooting in the 90’s. He had a great sense of humour, was a fairly unconventional personality and a great shot.

Some of the 3P influences show in the pistol grip angle and wide fore end.
He made up those stocks in a very simple low cost laminate and handful of BC shooters used them years back. I have one sitting in my safe right now.
The bedding and pillar installation looks a little rougher than what I saw as examples of his work or other local guys so I’m not sure who did the fitting and bedding. A shooter from Washington state had him make up one of those stocks in a beautiful two tone Walnut and it was finished to perfection. Otherwise they were the light Color as seen in yours.
Hope that helps shed a little light.
