I am glad the you got it, it was a great deal.Although a nice fork, I am not sure that it is original to the frame......none of my "P"'s have the type of lugs that you present, but I don't have any early "P"'s to compare it to,...so perhaps earlier ones have lugs like that.
In the last photo it looks like the rear drop has been bent, if so go gently when/if you try to open it up, in any event experts will chime in on the fork as well with advice on the rear drop if bent.(optical illllll)
Best, Ben

Cenilli lug.....so perhaps you are right about the front wheel bump and slight opening of the HT
