Magneto switch box & Oil Pressure gauge - Need help identifying aircraft

[AusA380]

Hi,
 
I recently went to a militaria swapmeet and picked up an oil pressure gauge and a magneto switch box from an aircraft. I'm not sure which aircraft they are from and i'm hoping people on here could give me some information.
 
From what i've seen on the internet, the magneto switch box appears to be from a British aircraft. The Spitfire looks to have a similar switch box, but the toggle switches are different from what I have. The Lancaster/bomber toggle switches appear similar to the one I have (Thick ends instead of ball ends like the Spitfires).
 
I'm unable to find any information on the oil pressure gauge. It has the text 'Mk VIII C No. 5064' and 'J. Tomey & Sons B'Ham' printed on the face of the gauge and an A & M with a crown stamped on the back. Mk VIII C is a Spitfire variation, but i'm unable to find a photo of a Spitfire cockpit with this gauge.
 
Any information would be appreciated.
 
Thanks
