Thousands vintage beads, Edwardian jet sequin beaded evening jacket, delicate M

I had this from a very very very elderly lady when I was a girl. I loved everything Edwardian (still do) and sang Edwardian songs (still do...look me up! Patricia Hammond) and she gave me this. Now of course, I've not ever sung in it. Of course I've not worn it. I have kept it carefully in a box. I have lost count of how many different styles of bead are on this, it is staggering. Square, round, baguette, little hollow leaves, small, tiny, large...The incredible incredible care that has gone into this! And it's so delicate. Gossamer! It is astounding. I shouldn't have it. A costume historian should have it. So here it is. Please please give it a cherished home. Restoration project? Art piece? Photoshoot? I have no idea where to put the price. The jet alone must be worth it. It is on the most gossamer-fine, cobwebby fabric which of course is frayed and torn, as it was when I was given it back in 1985. The inventiveness of the patterns! Maple leaves? It is from Canada! If made to close it is 30 inches around the waist and it is 40 inches long from top of neck to longest point of hem at the back.
