Can you stand back and get the whole thing,,both pieces in one pic ?? Looks like spun brass,, the #6 would indicate the size which means they made a bunch of them !! Same way cast iron is marked with a number for size !! Those pieces on the side would mean to me that either it had a handle at one time or that it sat in a holder of some sort both of which are gone !! Doesn`t really look like a mortar to me because it is flat on bottom and most are rounded !! Need to see the pestle !! I wouldn`t buy it !!
