Dual oil gauge identification

[fch630]

Hello all

I picked this up at an army surplus shop in the summer and have had difficulty identifying which plane it is from. It’s dated 1963 and the manufacturer label says “Smiths Ratiometer oil press and temp indicator”. It’s also got the stores tag still attached but unfortunately most of the writing has rubbed off. I’ve done some research and can only find similar gauges which go up to 80 or 100 psi. My best guess is that it could be from a V bomber, but would anyone have any more information? Thanks.
