Largest vise ever? - photos

From a followup message, looks like yes, it was a wood model. Here's the cool part, from a 1965 edition of The Athol Daily News:

An eight foot tall giant model of a vise of wood and tin that has stood in front of the factory at the west end of South Street since 1919 is to be removed. Once the symbol of the former Athol Machine and Foundry Co. which has been out of business two years, it was constructed for the home coming parade for World War I veterans on June 16, 1919 and displayed on a float with a dummy of the Kaiser squeezed in its jaws and Uncle Sam at the controls.
