This is a speaker grille and instrument (?) bezels out of something. The only metal parts are the grille mesh and the chrome pice that goes down the center.... the rest is plastic.
Mercury...something in the '46-48 range. Fits same dash stamping as Ford, which has different plastic arrangement.
Dependable HAMB..... took less than an hour..... LOL These will be for sale once I figure out a value or if someone makes an offer before I post in classifieds.
