There are only 3 possibilities for a Pentium 4 - 423, 478, and LGA 775.
It's not LGA 775, only faster processors use that, so that leaves socket 423 or 478.
The 1.4 GHz is probably a socket 423 judging by the fact that it's similar to a socket 370. Here's a pic of a socket 423 P4:
Is the second one the same as the first one or no?? It sounds like a socket 478. Socket 478 has pins on it, I think you're thinking of LGA 775 that the pins are on the motherboard. Here's a pic of a socket 478 P4:
