Interesting Taxco 3D Articulated Turtle Keychain ?

[fireyfoxy]

I found this wonder piece in a thrift shop last week and i have been researching vigorously with no results.I don't know but it looks to me to be a keychain but i am not sure .It did have a gold wash on it at one time as some of it remains on the turtles back.The keychain part has a screw off tip.He is 3D and he has articulated joints.His head legs and tail moves and jiggles !The stamp is as follows TAXCO MEXICO SH 925 he also has a eagle with the number 3 on his foot.Who is SH ? and has anyone ever seen an item like him ? Thanks in advance !

There are 2 SH marks in the hallmark book but neither has a name known.
