How can one obtain basic info on older film cameras?

[Dave Wooster]

I have been learning about point-and-shoot film cameras on my own using several such cameras that I picked up earlier in the year. But I hit a snag when I couldn't find manuals for these cameras:

Olympus Infinity Twin (switchable 35/70mm) or AF 1 Twin,
Olympus Promaster Zoom (to 70mm),
Ricoh Shotmaster Zoom II P Date (to 105mm),
Yashica ImageZoom 70 SE (Red-eye Reduction),
Canon Sure Shot Megazoom 105, and
Konica Z-up 150 VP.

Part of the problem seems to be that cameras have different names depending on where they are sold. Is there a resource somewhere that tries to list all the models, and the various names for them? Do you know an alternate name for any of the above?

Is there a resource somewhere that has just the specifications for most all cameras? For the above ones?

And of course, what are the possible sources for old camera manuals?

Thanks for reading my first post here,

Olympus Stylus Zoom 105 DLX, and before that,
Ricoh FF-90 (and before that, FF-3)

Just google the history of the brand. It should give you a history of their line of cameras. I do it all the time.

If it's not here, it's probably not anywhere.

BKMOOD, please post an example of words you search on in Google to find the history of a brand, like Ricoh. Thanks.

Correction:

My Yashica is a Zoom Image 70 SE, not an Imagezoom.
