Hi Imaginos,
First of all, whatever you do, don't clean it, other than a light rubbing with a soft cloth. If it is bronze, and not a spelter figure, over cleaning it will reduce its value dramatically, sometimes by half.
It would be helpful if you could post some clearer photographs, of the detail, the patina, the signature, the base and the underside of the base. Rough dimensions would also be useful.Any idea what the base is made from?
Do you know whether it is actually bronze or possibly spelter, but even if it is spelter it potentially still has quite a bit of value.
