What is your question?
If you are asking us to tell you what we think about the caps and screws, why are you showing us photos of everything but?
They seem OK, typical Wassily chairs in average condition.

These are the best photos I have of the caps and screws unfortunately, so I tried to post images where you could get at least a glimpse of them (not in the first photo which is just an overall view, but in the second and third). I understand that they are not ideal. Really, though, I'm wondering if there is anything else I should be looking for besides the caps and screws as those have already been written about a lot here.

In the second photo
I see a joint in the tube at the floor, centered. Is this a feature of all Wassilys ?

Quality. Good quality is the ...
Quality. Good quality is the first thing to look for.
Obviously looking for the original labels/ stickers is a easy way to ID.
I have 2 Wassily Chairs that were produced by Gavina in 1963. Knoll produced them after 1968 (by purchasing Gavin group) They have a label giving that info on the middle back horizontal chrome bar. However those stickers can come off over time. Later versions of Knoll wassilys have a label on the straps. Sometimes even if the sticker is gone you can still see proof/remains of a sticker being on the piece for years.
Yes, there should be a small line connect on the bottom chrome, the interlock with each other.
Other than that the screw and caps (or lack of caps) is key.
I Thought the leather straps look shoddy, as in not quite right, but my partner disagreed with me. I was surprised to see the leather peeling like that - I thought good quality leather (like knoll used) would not peel like that but he said any painted leather could do that.
Just need high resolution photos of key areas to be sure of anything, camera phone photos just don't cut it.
The bottom line is they look good and will last you a long time. I recommend putting plastic tubing over the bottom to prevent he bars on the ground being rubbed and worn away.
If you are planning to sell them, now is not the right time - vintages can be purchased for less than newer, less well made ones. Perhaps the market will bounce back as they are great chairs.

Thanks so much for your...
Thanks so much for your advice! I'm meeting with the seller to take a look at the chairs in person next week, and I'll keep all of your comments in mind. If they look right I will definitely buy them - I love the sleek lines and shape, and they will be fantastic in my apartment.
I may try to touch up the leather a bit in the worst places and definitely will add some plastic tubing as you suggested.
You're so right about the prices too. New chairs are retailing for $2264, but these older chairs are great and surprisingly inexpensive. I like that they are vintage, and I don't even really mind that the leather isn't in the best condition. Thanks again!

Twenty bucks
says you'll sell them within two years.
Everyone buys those chairs; no one keeps them.

The chairs pictured above were not produced by Knoll. The end caps are wrong.
And the Wassily chair is probably the most uncomfortable of all modern classic chairs.

Unfortunately true. Seems like the space gap in the lower part of your back makes this chair very uncomfortable. It's a pity.

Pic please
Need a pic of the caps - up close please.
opinion on the chair weighs heavily on this. The pic makes its look like they are capped - but perhaps not.
Better pic please.

Comfort?
I'm surprised people commenting that wassilys are uncomfortable, that's been the exact opposite of my experience. Granted it's not the chair to snuggle up and nod off in but when I need to read or work on something I found the chairs very comfortable and good on my back.
Granted I'm female, only 5'7 and slight of frame so maybe that makes a difference. My partner, who also posts on this acct., is a guy, bigger than me, and he thinks their comfortable as well.
Ah well. I also think Eames arm and side shell chairs are very comfy. I've used a arm shell with a tilt base for the past 6 years in my office and love it. But I've also heard people complain the fiberglass chairs are uncomfortable.
Probably has a lot to do with body type and preferences.

Really? To me it doesn't appear the ends are capped, but I could be wrong. Is there something else there that looks incorrect? Unfortunately the seller sent me a bunch of pictures, but none of them shows a great, high-res image of the ends so this is the best I've got for the time being. Once I see them in person I'll take some myself.

My photo isn't much better..
but the caps should be seamless, with no slight bevel to them, like those pictured above.
