Thick gauge silver tubing

Hi everyone. A close friend of mine who is a silversmith has a
broken computer and so I’m asking this on her behalf.

She once obtained the following, but can’t remember where from, and
I’m hoping you can help her find:

Thick or extra thick walled sterling silver tubing. The piece she
still has left, has an outer diameter of 3.64mm and an inner diameter
of 2.05.

She’s tried Metalliforous and Rio, but she says it’s not the same as
what she had.

Any ideas?

Jessica thanks you!

You may want to try Hauser & Miller for the thick wall sterling
silver, they have quite a selection. 1- 800- 462-7447
