Thanks, I am taking a trip to Toronto next week in which I plan to shoot B&W. Originally I was going to use my Yashica MG-1 for the trip but then this beauty fell in my lap. I hastily put a roll through it to ensure it works.
As for the handling, I like it. The mercury battery still works and I am very happy with the metering. I have an indoor picture of my daughter near a bright window that came out nicely too. It's smaller than the Yahsica, which is good and bad. I was able to fit the Olympus in my dress pants pocket (barely and without leather case) which I can't do with the Yashica. Loading film is a breeze, the teeth really grab on nicely to the sprocket holes in the film.
Looking forward to spending more time with it in Toronto and shooting some good street scenes. To answer your question the lock is on the Canadian side in Sault Ste Marie ON. It connects Lake Superior to the other great lakes. The Canadian lock is for pleasure craft mostly, the American locks are much larger and accommodate the laker ships.
