They probably froze in that location once before as well. That doesn't look like I'd expect the original plumbing to look: I suspect those solder joints are from an earlier repair from freezing. and if you look further down you'll see the other end of the new pieces that were put in.
We've owned three old houses. The first (Zion, IL) was a real mess (no heat to 2nd floor), asbestos/concrete shingle siding, a basement that flooded with every rain (though our young kids loved to see the salamanders that swam around in that), a flat roof over a rear one-story addition. I learned a lot about home maintenance in those years (on an assistant/associate professor's salary).
The second was a really nice place, a block from Wheaton College. I think the only thing we did to it was put in a nice gas fireplace and a backyard fence. I'd left academia by that time. It was a very nice (brick) place, with a finished basement and 6(!) bedrooms, a grade school two blocks away and a middle school almost across the street. Best heating system (forced hot water) that I've ever had.
The third (and current one) is on 6.5 acres, requires more tending to, and was built in the 1970s in NC. I'll leave a lot of that to your imagination, but I've put a lot of electrical work in it, some plumbing, and my wife and I built a barn on it (a skill I'd learned in graduate school). It hasn't been much of a burden, and my skill set really expanded over the years. But currently (as I look out my office window here), I see the 40' trench that got dug last week to open up the septic leach field. That will likely get fixed some time next week when the weather lets up a bit.
Yes, the joys of home ownership.

But I still think it beats the alternatives -- plus I have this HUGE collection of tools of all sorts.
