Well Dirty Doc,
Lot there to pick from.............not really sure what you want to hear.
But I suppose I'll leave it to someone your side of the pond, as serial numbers washed out in any country, are as popular with agencies like the ATF, as a porcupine in a Durex factory.
Simply put, you have two .45's and a knuckleduster knife, I am sure someone will pick the bones out of what you potentially have and respond. Good luck.
