Hehr Style window with aluminum frame. Was salvaged off of a 1950 Spartanette. Rough opening is 19-1/2" W x 4-1/2" H. Overall 21-5/8" W x 6-1/4" H. These windows all have the original seals and screens but may need replaced. Has a Keene window operator, in good working condition, but will need to be lubricated. Inner frame may need straightened out but overall in good condition. Pictures may vary but windows are comparable.
