Possibly getting a Riley Hopkins 6x4 but need some info

I found this press on fb market place for a really good price in my town and for the most part it seems good, only issue is I think they’re might be some pieces missing but I’m not sure. I don’t necessarily need a 4 station, but 6 color would be nice though, my main need is the micro regs. In the first picture is the print heads for the press I’m getting, the second is what the heads look like on the RH 6x4 available on the website. Like I said it looks like there are things that are missing. I’m not sure if this might be because this press is a few years older and maybe in the newer models like on the website, they’ve made some upgrades to it over the years, but even then on the print heads there are the extra screw holes. The lady selling it to me just got it from her uncle who moved across the country and left it behind, so she doesn’t know much about it. I asked if she maybe had any of the hardware for the press stored away or if her uncle still had it and she said no.

So I have some questions for people who have 6x4 RH presses:

If you the same press, does it come like this?

Are things missing from this press?

If things are missing and I bought it as is, would I be able to buy individual micro reg pieces from Ryonet and install them after?
