I found these two in a box that an antique dealer had, he was trying to sell the box for awhile and could not it was filed with mostly world wide stamps. I wound up getting everything he had in a plastic crate for $75 including a 1930 Scott catalogue a 5x7 book with 1800 + pages.
Can any one help ID these for me?

The stamp on the right appears to be darker and less defined than the left one. Is the one one the right a 206? and 182 for the left?
Thank you for the help!
