U. S. Army Receipt For Goods Dated May 16, 1944

I had this receipt in a box of items and thought I would share it.
It is for items purchased by the U. S. Army from W. Gregory & Sons. It is hard to read the handwriting, but here is what I think it says. "4 pieces of tube, drilling & fittings 4 pieces for night wires. Making 8 double brackets. 40 M.T. (?) 54 nuts. If you have any other ideas, please share them with me.
As you can see, this was in England and dated about three weeks before D-Day.
