Sarawak Constabulary badge?

Is this badge an original? I confess I'm getting a bit nervous about all the copies on ebay so a little worried when any shiny new-looking badge turns up.
The seller also has other colonial police badges Aden, Gold Coast Police that I'm unsure of..the obverse of the last two look good, but the reverse does not have the impression of the letters..also the lugs might be new or maybe someone's just cleaned them up?.
Would appreciate the forum's view as I want to bid but not sure if it's the real thing...

For reasons that I wish to keep to myself, I would steer clear of buying anything from the seller.
