Looks and feels like age - but how much?

Found today in a second hand shop

The blue, yellow and green glazes have a rather loud hue that I'm not used to seeing on porcelain (it's more akin to South American pottery) Famille verte maybe?

The three footed design seems out of character and likely implies export porcelain but that's a layman's guess (and would still be a fairly wide time range)

There is a singular spur mark in the center bottom (where you would expect to find a factory mark / signature

Height = 5.75" - 14.6 cm
Circumference = 20" - 50.8 cm
Weight = 1.5lbs - .7kg

Any one out there have a hit as to time period?


Cheers ~

 

According to Jan-Erik Nilsson "As a rule no Chinese export porcelain from the 18th century have any marks. Most 19th century export pieces also lack marks"

so that could narrow it down to a 150-175 year window
