I need to make new brake pipes on the Disco 1. What are the fittings? 3/8, 10mm, -3AN?

I'm not just ordering replacement parts, but I need to make modified ones. Ideally, I'd use a banjo bolt for a tight right-angle into the D110 calipers I'm using. I either need an adapter from the extra length stainless braided flex lines I have already, or a short pipe. Yes, I can bend the existing pipes, but they're really too long. I'm hoping to find some universal parts that I can use, or make some pipes. I don't have a flaring tool and I don't even know what kind of ends to get.

You can get pre-flared straight brake hardlines with line nuts attached in many lengths (plus adaptors if needed) at any Autozone, Advance, etc.
RockAuto also sells some premade hardlines.

flaring is easy just takes a few practices.
make sure its a good flaring kit like rigid - dont go cheap it will twist and bend the pipe
I redid all the hard and soft lines on my 98 disco 4yrs ago.
I got all my parts from napa
