It measures 1 and 5/8 inches tall.
It appears to be signed but the mark is faintly stamped at the edges and thus only partial.
First there is a G with the (partial) word ASINO or ASINU or ISINU or USINO below.
There is also a hallmark. It is a square. It is so tiny that even with magnification I can only assume that is is a profile of a man's head. When you turn it upside down, it looks like a rooster. Next to the head or the rooster is an N8 or (upside down) an 8N. The 8 and the N are on top of each other.

The bottom has been scratched, it appears intentionally so. I see no evidence of a base metal and do believe it is solid though if this needs to be moved I will accept my punishment gracefully.
Thank you!
