Scadam, there are huge differences between an original SOS and a blue SOS. The originals as everyone knows had a lot of problems. As with many things throughout history, the problems were addressed in the upgrade. There are tens of thousands of blue SOSs in both red and blue Fords out there working every day. The blue ones have a drain plug on the bottom and the cover has a sideways slant on the right end of the hump. I urge you to be a part of educating people on the difference.
Showcrop, this is a good start, however it is not entirely correct. I have a '63 4000 with blue transmission, casting # C0NN-7006-B, that has no drain plug in the bottom of the case. I think this was a running change. I also have two '64 4000s, transmission casting # C3NN-7006-B, that do have the plug.
Casting numbers are more important to identifying which transmission is installed than describing slants and plugs. The two numbers listed above are blue (DDC) casting numbers. A 312259 casting number would indicate a red (ORC) transmission which is, as you have said, less desirable. I do know there are still numbers of them out there working flawlessly, however.
Having said all this, I have seen the extremely rare exception to the casting number rule. I have run across a prior 4000, equipped with the blue transmission, with a casting number of 312259.
