Salvador Dali Bronze - Wailing Wall on Jerusalem Stone base

Salvador Dali Bronze Wailing Wall sculpture - Silver Patina.  Signed and No. 194/250 mounted on Stone base  etched in English and Hebrew "Jerusalem Stone".

I am looking to authenticate this piece and get an idea of it's value.  It came without COA.  Is it real or a 'fake'?

Here are the details:

Bronze - 9 1/8" max width, 13 1/4 max height, depth approx 12mm (1/2") and thickest points.

Stone Base 1 1/4" tall, 3 1/8" deep, 11 3/8" wide

Overall size 11 3/8 x 14 1/2 (including base and bronze)

Weight - Bronze 7.0 lbs, base 4.0 lbs, total 11.0 lbs.

The bottom edge is ground flat across much of the length to mount flat against the stone.  There are two different size mounting holes drilled in the lower edge.  Both are directly tapped, no insert with different threads.

There is an identifing mark on the back - please see the pictures.  i would like to know if this is from the foundry or producer possibly?

There is very good detail in the bronze, although it is different than others that I've seen pictures of in that the vertical and horizontal lines deliniating the wall stones are not present in some areas of this piece, but are in other examples I have seen pictures of.  In many areas I see much more detail than pictures of other examples.

The back of this piece is not generally smooth as I would expect.  There are clearly worked/cast marks on the back of the work.  It looks almost like the back was pressed against an old plate or something.

Thanks in advance for opinions/comments/evaluations
