I'm rather unclear about what your statue is made of/from , Mike .... also , do you think that the etching you mentioned is an actual signature , or simply a 'marking' , casting , etc .
What size & weight is it ?
I found 'your' statue in bronze , for sale in N.Y.C. for $4600.00 - it's listed on e-bay as :
31" Guillemin & Barye Orientalist Arab Sculpture .
