It all looks about right to me. You don't usually see those extra "brazing lumps" on the older cars, but you do on the "squaretail" models. As to the cracking at the base of the "B" post, I wouldn't worry about that, either. Given that the car seems to have had a rather indifferent repaint, that could just be filler cracking a bit. I suspect that, like the sills, there's a bit of brazing at the base of that post, which would have been "factory"!
