There was another member here who had it done on his A5 clone, I think the name was BlackPatch? It was a place in Alberta and based on the photos all the machine work such as the thumb relief cut at the rear of the loading port etc was very detail accurate.
Do a search for that user name and look for photos of his A5. The shop name was visible on the tooling I think it was the action fixture in one photo, or just PM him as well.
I had mine done by the late Mick McPhee but it was a hybrid version I copied from LRI down in the US.
