Front Fenders and Seat ID needed. 1939 Mercury or?

[gz]

Hi-

Helping a friend ID these front fenders and seats. There are two sets of front fenders, one set is primered and one set is original with the inner fenders.

There is a bottom seat cushion and a matching rear cushion with original springs, etc.

They had 1939 Mercurys in the past, so I am thinking these are 1939 Mercury?

Would they fit other years and models?

They will be for sale and I can supply better photos, but I want to make sure what they fit before I advertise them here.

Thank you in advance.
