The one on the left looks like either SG D129 issued from 1953 to 1959 or SG D140 issued from 1958-1960. D129 has a watermark. D140 does not have a watermark.
Both varieties have two shades: D129 has carmine/yellow green and carmine/deep green D140 has carmine/deep green and deep carmine/deep green
The stamp on the left is definitely SG D129 (watermarked) in the carmine and yellow-green shade. There are also deep yellow-green and deep green shades too.
The stamp on the right is SG D69 with a nice little flaw on the bottom left serif of the '1'.
