How old is this oil painting?

I can't quite work out what's going on with this painting.
On one hand it seems to be quite old looking at the back with those old nails and just the sort of age on the wood.
On the other hand it kind of doesn't have an old feel. Like the bezel if that's the right word that kind of inner frame around the painting sort of seems to be newer and deliberately painted to sort of be slightly distressed.
Then it has the glass presumably added later and the glasses in very good condition.
The canvas itself looks quite old at the back.
Perhaps it was a case of this being put into an older frame and at the same time the glass added?

What are people's thoughts.
By the way I'm not seeing anything that I haven't showing in the photos so don't take my interpretation as being from any greater visual information and what's here and I'm happy to post more photos of specific bits.

Looks like a fairly amateurish copy of a Boucher possibly done by a student for a saloon or boudoir.The frame looks old but seems someone did a mediocre repaint and used masking tape to hold the painting in place.
It could be a late 19th century copy on a reused canvas,it could also be newer (i'd guess no later than the 40's or 50's).
I'd take it apart and examine it-don't think you'd be damaging a masterpiece,plus you never know what you'll find.

 

This piece has two frames so what you call a bezel is just the inner frame. You don't say the size, but it's not standard so I'm going to guess the inner frame was original to the piece and the outer frame added to make it more traditional. Or someone wanted to make it fit the outer frame so added the inner. The canvas looks machine made.

The painting itself is definitely student or hobbiest work. The hands are really a tell here, especially the lovely lady who's hand on shoulder has 5 long fingers, so 6 total if we count the unseen thumb. The original has the correct amount of fingers. The style looks early to mid-century to me, in the faces.

 

Here are some photos of the 2 frames seperated.
@mirana I agree the outer frame makes it look more traditional and is maybe older not sure?
I also agree that the painting is quite modern now that I've taken the glass off it doesn't look very old.
I'm glad I took it apart because it allowed me to remove the glass which actually makes it present better without the glass
Without the glass you can see the brush strokes more so it looks more like a painting.

I had actually hope that it was an old but amateur original I certainly could see that it was amateur but I was hoping that it was maybe 19th century.
I definitely like the outer frame style

 

From the hair and make-up (those long, thin eye brows!), I'd think 1930s heading into the 1940s. The jeweled tones of the drapery works with that period too.

Its much prettier out from under that glass.

 

No glass:
(note that the inner frame does sit in flush, its just posed here)
I suspect someone spent some money on this at some point to get the inner frame made (it fits perfectly the canvas and fits perfectly the outer frame) and the glass cut.

 

You don't usually see paintings behind glass. Only paper media like pencil or pastel.

 

I think the glass was put in later when the newer inner frame was added. The inner frame has been made to look distressed.
It is definitely a painting. Has 3-dimensionality to the paint.

 

To my eye, looks like a frame contemporary to the work that's been dropped into an older frame.
