Ok guys,as I try to clean up my garage of some of the old stuff that been laying around for years.Here's another one.Its a license tag light housing,NOS never installed.Only markings is "Guide LIHT 61".The base is oval shaped,long portion of the oval measures 2 5/8",the narrow portion of the oval base measures 1 3/4",the heighth measures 3 1/4".I kinda think its for early model cars(maybe 1946-1950 Chevy,Old,Pontiac,Buick,Cadillac,or Possibly late 40's early 50's Ford or Mercury). If anyone has an early Guide Catalog for lights and housings that could look this up,I'd appreciate.I'd like to list this on E-Bay,I know someone out must need this part.BOB,By the way thank you for creating this section on the sight,great idea!!!!! Thanks John
