Thoughts on this hand gonne barrel please

[grauritter]

Hello everyone!

I just got an original barrel for a hand gonne, but I don't know it's time or area. The flowers seem asian in design, but the trail on the back looks just like one of dutch origin posted on handgonne.com.
It's condition seems excellent, so either it was never put into service, or it's not really as old as I'm hoping it is.

It will arrive next week, and I'll post my own photos. But for now, here are the photos the dealer sent...

It's cast bronze and about 5 inches in length.

Would anyone here be knowledgeable on the date and area this might be from by chance?

Kindest regards,
-Jason
