I definitely don't know much, but I may have some ideas to offer
The crazing doesn't always necessarily mean age. It can be due to exposure to the elements...too dry, too wet, extreme temperature changes...I've seen some fairly new pieces of my own begin to deteriorate in this manner in a matter of months as they were in a metal storage area. The glaze just couldn't handle the extreme heat and cold changes.
But what I find unique about this piece is the eyes. In western culture, owls are generally a symbol of knowledge because of their wide and sharp eyes. This one has very narrow angular slits.
In many eastern and native american cultures the owl was significant to much darker forces. Often appearing in myths and legends as a death bringer or sometimes even embodied demonic presence.
With those thin angry looking almost judgmental eyes, the dark colors and the lack of features that draw you to the horn like protrusions of the head, I'd look into pieces from eastern cultures.
As well, I recognize the painting style, but for the life of me can not make a connection in my head to what it was called. Finding that out, as well, may help to date this little critter
Hope some of that helps, and good luck!
