So does the prism on my Pentax H1a. You'll see Canons marked "Bell & Howell", too. In fact I seem to recall at least one Canon-made body - and some lenses - that said B&H only, no reference to the manufacturer except the small "Made in Japan" markings. In each case, the US company was the importer/marketer.
