Jim:
Another detail that ties 62 and 41 together but separates them from 8 at TF is the torsion bar hole, which is covered in these 2 shots, and not on 8 from the TF. Also, the shape/angle of the flare near the torsion hole is different looking on 8 vs. 62/41. Singer's notes would seem to be a pretty reliable source.
