take a look here:

According to those descriptions I would think 6.1 or 6.3. I am not sure how tin oxidizes, so I am not sure it falls into the 6.1 description of "dark color".

Here are some pictures I found of what should be Y# 6.1, 6.2 and 6.3. I didn't found any Y# 6.4:

Y# 6.1:



Y# 6.2:



Y# 6.3:




Maybe you can see some differences but it's a tough one to determinate.

thank you for the replies

i dont really see a difference,
