I'd say my opinion would be Chinese manufacture , with a fake "Da Ming Xuande Nian Zhi" cast hallmark .
Most often , in my experience , these hallmarks are very well defined & crafted in the 'genuine article' , very much unlike the one on your item .
I will guess that yours is cast brass , with hand-carved features on the obverse & that it comes from 1930's thru 1950's era ... &/or 'home-produced' during the 'Cultural Revolution' , when many rural Chinese were forced into home-smelting of pig iron for the country .
I'd identify it as a 'tourist-type' item .
The cool thing is that the carver/metalworker/artist signed it on the reverse - most of these types of items I've seen lack a sig .
