Unknown object

[Burney Davis]

Can anyone ID the object in the pictures below? It was grouped with a number of WW2 British fuzes. Measures 5cm x 2.5cm and is extremely well made.

Markings on the main piece are

PC830 A/1
PRO PAT
No 12591/38

and on the attached plate

PC842/1


Thanks in advance.
