For insurance purposes, you're probably going to want to get to a typewriter shop with an experienced tech. Take them your list and all the photos you have, then have them come up with fair values for working machines.

There is a Type-In here in Philadelphia at Philly Typewriter down on East Passyunk Ave. (pronounced: pa shunk, like pass skunk). They advertised on the local NPR station and all the regional affiliates, so who knows how much of a big deal this will be. Starts at 10:00am and goes until I'm not sure when. I'm hoping to make it and will be bringing the Facit TP1, possibly the Remington-Rand Model 7, oooh, there's also the restored Corona Four to show off...
I'll definitely have to take the car, not the bike, if I'm bringing more than one typewriter.

One thing you may need to do is get rid of any porous items that are in the typewriter. The typebar rest and the key bar rest come to mind. Typebar rests are easy to replace with new material (felt, leather, rubber, etc.) The material where the key bars come to rest is far more difficult to remove and replace usually, but as it is very close to the hands, may pose a significant source of smell from old perfume, cologne, cigars, or whatever grime may have been on the hands of the user. 
I've used scrubby solutions of baking soda and water, baking soda and vinegar, baking soda and dish detergent, all sorts of stuff. I have caked on baking soda and water paste as well. I had a similar problem with an 8mm motion picture camera I was restoring for use a few years ago. It was so pungent with bad cologne that it couldn't be brought to one's face. I had to remove the leatherette from the camera, soak it in Bronner's liquid soap and eventually the smell left it. Basically, if the scent is suspended in oil like most perfumes, an oil, surfactant, or solvent is necessary to remove the offending odor. 
Don't forget to soak the keys in whatever you're using to remove smell, those are also often a source.

A couple years ago, I took a chance on a locked S-C Holiday case that was listed at 12lb in weight. It cost me $6 + minimal shipping from Delaware. Turned out to be a very nice Tower President.

If you can find the threaded stud that came off, you could use some JB Weld and put it right back on. This is not a stressed part, but needs to be able to move vertically in the slot in the carriage to allow the paper feed to release.
