I replaced all the brake parts on a '55 3100 last year, including the master cylinder, new steel brake line tubing, hoses, and wheel cylinders.
I found a little tool at my local auto parts store called a "one-man-bleeder" or something like that. I think it cost about $5. It was a little plasitic tube with a fitting at one end that fit over the bleeder valve on a wheel cylinder and a little check valve in the tube that allows flow in one direction only.
One end slips over the bleeder valve, and I put the other end into a clean plastic jar. Fill the master cylinder, open the bleeder valve and then gently pump the brake pedal.
Since I was doing this myself, I wasn't able to see the brake fluid coming out, I just pumped and refilled the master cylinder until I guessed was enough. The fluid that is captured in the jar is clean and reusable, so I'd just pour it back into the MC and go onto the next wheel cylinder. I started with a rear wheel cylinder that I thought was farthest from the MC. Worked fine.
