I think I have told you this before, but I've actually been in bustling downtown Concrete.
Here is a link to Nauticapedia informally run by the Maritime Museum in Victoria. The folks at Nauticapedia have compiled a list of all boats and manufacturers they can find of boats built in British Columbia. If you go into the tab that says something like Vessel Search or whatever and input Capricorn (my boat) you will see a picture of it before I undertook a massive refit, but it still pretty much looks the same.
Anyway this link takes you to Grenfell manufacture in the listing of manufactures and boats, you will see it goes on for two pages and a bit:

Here is a link to a number of Grenfell images, one of those boats is in my marina not to far from my boat. When I was bringing back my boat after refit, the owner of the Grenfell was by his boat working on chores, when he spotted me, he gave a big grin and a wave.
