ANTIQUE VINTAGE BOOKBINDERS TYPE HOLDER ? For Sale

SO I AM TOLD THIS IS A TYPE-HOLDER . THE BINDER COMPOSES A WORD WITH BRASS TYPE , THE SCREW DESIGN KEEPS THE WORD CENTERED . THE WHOLE THING IS HEATED SO TEXT CAN BE IMPRESSED INTO LEATHER , AND GOLD LEAF WITH \"GLAIR\" IS BONDED TO THE LEATHER . THE TOOL IS ROCKED , BY HAND , FROM SIDE TO SIDE , REQUIRING MUCH PRACTICE TO GET IT RIGHT . WHEW !!!!! I CAN NEITHER CONFIRM OR DENY THE FORGOING IS CORRECT BUT ANOTHER ER SAYS IT IS SO !!!
