After seeing the pictures sent here I decided to take one off and see what I had up close. This is the embarrasing part. All the bleeder screws were there but just covered very well with 60 years of crud. The twelve point wrench I was trying to turn them with originally would not break them and they looked like they were smooth and solid with no hole in center so I assumed they were broken off but after getting them off and hitting them with a wire brush for a while, I could see they were there, just full of hardened grease, mud, oil and who knows what else. Got them all broken loose, cleaned out and re-installed and bled. Now I have good brakes. thanks for all the info and pictures.
