The latest safari and guessing game

When I stopped by the local antique mall this morning, I saw this little poster in the window:

This was promising. Indeed, there were quite a few typewriters to be seen, some that had been in the mall for a while and some that were new to me. Prices were pretty good, and I ended up taking two machines with me.

This Smith-Corona Coronet Electric was a mere $19.99, with a pack of correction tabs.

This Olympia SM4 had its own correction tabs, and a few issues: the backspace key and tab set key were in a low position, and the platen was hard. Price: $37.50.

Olympia Report Electric, $29:

A ’50s Smith-Corona Skyriter for $39:

Tom Thumb, $50:

Here is the "vending area"—they meant the area with snack vending machines. Realizing that there are people who come in especially looking for typewriters, the mall managers have evidently tried to round up a number of machines and put them on shelves here.

Remington Portable No. 1, $37.95:

Royal 10, $40:

More!

Royalite, $45:

I came home with the set of sheets that were displayed on the Royalite. They're for a correspondence course run by the International Typographical Union. The ITU was the oldest union in America, founded in Cincinnati in 1852. Elmer Brown was its director from 1958 to 1978.

If you like the stationery above, you can download a PDF of it here.

Back to the typewriters on display: here's a Smith-Corona Classic 12 for $40.

Here's a Remington 12:

This Letter-Riter was, as its label said ...

... very clean, very clean. $120.

Very unusually, the Letter-Riter included some of the original packaging hardware that kept it in proper condition when it was shipped from the factory.

This Olympia SG1 with the bent carriage return lever has been in the mall for a while. 

Finally, a Royal for $59.99.

So here's the guessing game. Which two typewriters did I buy?

The first person to post the correct answer in the comments section will receive a letter in the mail from me, typed on an International Typographical Union form. I'll post the right answer in 24 hours in the comments.
