WTB genuine sub insert

[Thurnau]

I am looking for a real Rolex sub bezel insert. I do not need a new one, and I would prefer one used and aged or damaged. I want to test an insert to see if the numbers rub off after soaking it in solvents (lacquer thinner, acetone, mek, etc.)that I use in my paint store. Basically I am trying to test the durability of the bezel before I spend money on a new sub. I am looking to buy it cheap as the condition of the piece does not matter. If some one wouldn't mind loaning it to me for the test, or selling me one for cheap it would be greatly appreciated.

I am not looking for a new or usable part, but more or less a damaged one you replaced after maintenance.
