Here is a rarer find then most of the machines in this thread.
A Yost No 4.

Dear Santa,
I would like one Yost upstrike typewriter.

Update on the $18 Densmore.
Its mine. I made a deal with the person who bought it to get it.

Uwe:  You have a good point there.  I'm still trying to get a list of what machine(s) she has, but it would surely be useful to get a little experience to gain a better sense of what I like.  I should mention that while this will be my first time owning a vintage typewriter, I actually have used a typewriter before.  Our family had one when I was growing up and I took a typing class in High School back around 1986 or so.  Also, even if I don't act on it until later I'd still like time to do my research beforehand on my "short list".

mre12ax7:  I agree that this looks like one of the hotter finds.  I've had no trouble locating multiple KMM's for instance leading me to believe that I can get one later on without much trouble. 10's appear more rare and should be followed up on.

And by way of an update, the Olympia SM9 is sold now since this morning.  A reminder not to tarry too long but to seize the moment?  I'm going to call the Royal 10 seller and see what more I can find out about that particular machine.  However, I will also try not to go too overboard until after Thanksgiving.

One more update about the Underwoods...  Apparently the Leader may have been a budget model, so it may or may not be superior to the older Underwood Portable which I'm still trying to pin down and get a price for.  This is taken from http://oztypewriter.blogspot.com/2011/11/underwood-portable-typewriters-1919_22.html

"In 1949, another model was added to this line, the Leader, which was a much more basic version of the Universal-Champion."

However, the Leader I'm looking at is an earlier model so I'm not 100% sure this still applies.

The leader was always somewhat of a budget model.
 

Why?
