It is very well detailed and has a button stamp on the bottom marked 800. It is signed also on the base E McAllister and it looks like there’s a date of 1986. I wasn’t able to find any information on the artist, but it is very well done. I don’t believe it is a solid piece, but it does weigh 200 g and 800 silver. It measures approximately 4 inches tall and 4 x 2“ at the base. Thanks for your interest.
