Thanks Blue 74 - 'your blood is worth bottling' - pulled the front off the motor sure enough both plugs missing.  Will try and source some here in Brisbane and hopefully there will be an improvement in the oil pressure.👍
 
also thanks to Gaz, that is how I have been driving the pump ie small socket on the dizzy drive shaft.  Hopefully I wont have to pull the motor now🤞     Will let you know what happens when I have put the plugs in.

That's great news however I suspect you will be missing the plug from the rear of the block also. It probably didn't leak yet due to lack of oil pressure.
I would slip a piece of stiff wire (A piece of windscreen wiper stainless steel backing works well), down the oil gallery from the front oil gallery hole and measure the distance to the rear, If it is the same as the block length the plug is probably missing.
I have attached an rear image of the cylinder block for you to see the location.

I encountered this exact problem when I built my first Pinto back in the mid 80s. It's amazing how quickly it dumped all the oil out the back hole of the block into the flywheel and straight onto my driveway through the hole in the bell housing for the clutch fork.
 
And when I went to Ford to ask for the welsh plugs the bloke at the spare-parts counter told me no such part existed. I had to point them out to him on his microfiche.

Checked using the method suggested blue74 appears the back oil plug(ball) is in place. 
Any suggestions where I might pickup a genuine oil gallery set of plugs. By my measurement one plug hole is 10mm+ the other 13mm + I purchased a 11mm plug from local engine rebuilder but it seemed to be too big and distorted when I tried to drive it home.
are the genuine ones an odd size?

Oil, oil glorious oil, spun the pump holding my fingers over the oil ports (finger in the dyke style) and a very slow drill speed had good oil pressure and oil squirting out of the cam spray bar.  Haven't been able to find plugs that fit yet but have ordered from Britain.
Thanks for all your help!

The 10mm is probably 1/8 NPT and the 13mm 1/4 NPT.

Thanks Jamman  - But not threaded, small welsh plugs.  Did think about taping them but not much wall thickness in the block.
Regards
Bob

That's good news the rear plug is in, Sorry I can't help with a supplier for welsh plugs however all I would do is ring around various engine re builders and ask them if you are impatient like me!

Just an update, I ordered a set of oil gallery plugs from two different suppliers in Britain via Ebay.   Both sets arrived here in Bris 10 days postage time.   They are installed and oil pressure problem solved, thanks again blue74.
 
For general information the genuine big plug measures 14.16mm the small one is 11.13mm, the ball measured 11.06 (the 14mm plug that I got from a local engine rebuilder measured 14.37mm and the 11mm measured 11.32mm both of these plugs would not go into the gallery [frozen] without distorting.  I only tried one brand of plugs, there may be others out there that might be closer to the originals)
Many thanks to those who took an interest and made suggestions.
Regards,   Bob
