HS 8 Redial

Hi

I have a HS 8 Fleet Air Arm watch with what appears to be a later replacement dial, certainly not original or apparently an in service redial? Is this style familiar to anyone, the numbers are reflective, possible silvered unlike the matt black of the real thing. I know that the sweep hand is a replacement.

I'd appreciate any comments as I'm sure I've seen the same dial on a boxed version of this watch, with the distinctive hooked 7.

thanks Stu
