Antique Priest Crucifix

This is an antique priest crucifix that was weird during exorcisms I'm not sure the exact year but I have done some research into this piece and I know that we're Jesus hangs on this cross there used to be wood inlay behind it this piece of solid brass and Jesus and part of the INRI piece above his head is held on by nails there is also a place to run a chain through this as a priest would wear around his neck. I'm not an expert on antiques but I bought and sold them for a while. This is pre1900
