An old French door

Hello and good afternoon, recently picked up a beautiful French door from a local salvage yard and I'm trying to get an estimate on how old it is. Wife thinks 50's but I'm thinking it's a replica from the 80's or 90's. Let me know if you have any ideas please.

 

In my research I've seen the hardware is usually a good way to date doors but unfortunately ours only has the door side of the hinge with no markings.

 

Thanks for the pointer!

 

Really hard to tell but the "ghost" of the door hardware and that shaded patina on the hinge make me think older. Maybe as early as the 30s, on in to the 50s.

 

Thanks for the thoughts, guess I'll let the wife know she's probably right haha.

 

JMHO. anybody's guess because they are still produced. these here look rather new. from what I see they are not massif wood.
mine are end-60s.
