Thanks for that, its interesting I didn't know that NZ would have had any enamel sign makers I'd would be interesting to see what other signs that they have produced, anybody have any other examples to share?. Looks like the more common Maori "New Zealand Agency Insurance" signs are made by Patent Enamel from what I can see.
Anyway, what is it.... "GEO Hadfield Wellington NZ" ? Can't quite make it out.
