Hey Barry, welcome to the site. My "mum" is from the Norfolk area, a few miles outside Norwich. Been over there many times throughout my life.
Anyway, the oil pump shaft should have a little press on washer that does not allow it to pull out when you remove the distributor. It sure sounds like you have no oil being pumped, especially if that shaft comes out with the distributor.
Pull the oil pan (I had to raise the motor a little to do mine) and you'll see the pump. Two bolts hold the pump in place - pull those and take the pump out. If the shaft is in place it'll come out with the pump. You'll be able to see how it all goes together when you get it out. As the guys on this site taught me, the pump screen will possibly show the tell tale signs of metal and obstructions. Cheap easy investment to replace the oil pump and it's drive shaft. A new oil pump is about $25 US. I bought a stronger "ARP" oil pump drive shaft for my rebuild. You can get it here; http://www.summitracing.com/parts/ARP-154-7902/
If you look at the picture you'll see the washer. Here's what can happen to the original shaft if something gets in the pump and jams it; scroll down to see the pictures when you get to this link. http://www.summitracing.com/parts/ARP-154-7902/
The other thing these guys taught me was that the first thing to do is to get a shop manual. Here's where I got mine; http://www.fordmanuals.com/estore/scripts/default.asp
Worth every pence!
