Unknown prison buttons

[Jamesb853]

Attached are scans of two prison buttons in my possession, with apologies for the poor quality, but these are the best scans I could get.
Descriptions as follows:
1. White metal, Kings Crown, PRISON DEPARTMENT. Backmark: V&R Blakemore Birmingham.
2. Brass, Victorian Crown, PRISONS SERVICE. Backmark: Firmin & Sons Ld Dublin.

I assume that 2 is from an Irish prison, but no idea about the attribution of 1. Does anyone have any suggestions please?

Hi James,
I would agree with you about 2 being an Irish version and would say the other is probably Commonwealth.

I agree, probably from the Commonwealth and look based on Police buttons, remind me of Cyprus items for some reason!
