Hi Cerjak,
I have another small example with engraved designs that was discussed
here. As far as age, I think your example is older than mine. I thought mine may have been second half of the 19th C, so I would say your chopper could be early 19th C, or even 18th C. As you note, the dating of such pieces is very difficult based on appearance, and any estimate of age must be very tentative.
Ian.
