84 Points, Typewriter Hunter

I'm a collector of various types of antique/vintage items (toys, farm tools, old bottles, war memorabilia, coins, stamps, etc.).

I came across 3 antique Remington portable typewriters several years back and am hoping to be able to identify their Model # and Date of manufacture, if possible.

I am planning on selling them but not without a bit more knowledge about them :)

I'm from Ontario, Canada.
