Hello Grant, are you able to upload pictures of the safe? A full front view with door closed and also one with door open 90 degrees will help if you are able, hopefully someone can then ID it for you.
Most members on here are probably ‘more at home’ and familiar with our British market Chubb’s than those for other markets, as they sometimes released different models, different specs and different names etc for overseas markets, but hopefully we will recognise it.
BTW the makers plate looks in great condition, has a particularly nice colour to it.
