No it wasn't. They usually had two view finders (for portrait and
landscape) with mirrors in each.

there were a *lot* of brownie cameras, most *without* a mirror.

there's no mirror on these:

Of all the URLs you have cited above only the first relates to the
subject of discussion, the *box* brownie. That site describes the
optional view finder available after 1900. At some stage the view
finders were built into the camera. e.g.
http://www.brownie-camera.com/50.jpg and later
http://www.nigel-roberts.info/images...ox-Brownie.jpg

More Box Brownies were built after 1900 than before and it is
virtually certain that most of these had view finders.

If you insist that the name Brownie includes more than the Box
Brownie, perhaps you should also include http://tinyurl.com/h5y8kdb
