Comparison shots - 1946 Ford Super Deluxe and 1946 Mercury Sedan Coupes.
Both models share the same body from the Firewall back.
On that basis, glass, doors and trunk lids are the same, except for different trim that distinguishes each model.
This car is a 1946 Mercury 114 Coupe.
Steve mentioned about a 114" Wheelbase Mercury.
These Mercurys were unique to Canada and buyers had a choice of selecting a Coupe or a Sedan Coupe.
The Coupe body style was never released on the regular 118" Wheelbase Mercury, only the Sedan Coupe.
Notice that the Mercury 114 used Ford front fenders and hood.
