Sounds like you got the small flap.
Here are the sizes and prices of the flaps:
Small - 9" W x 5.5" H x 2" D - $2,295.00 for Caviar + $100.00 more for lambskin
Medium - 10" x 6" x 2.5" - $2,395.00 Caviar + $100.00 more for lambskin
Jumbo - 12" x 8" x 3" - $2,650.00 Caviar + $100.00 more for lambskin
Did you get it on Ebay? I often see small flaps on Ebay listed with the medium flap's dimensions. I think a lot of sellers are lazy and just copy/paste other people's auction specs. Sometimes I see the East west bag with the medium classic's dimensions too! Now that is a big difference.
You got the small one that is 9". See the post above with the measurements. The one without double flaps is the east west (has no back pocket either).
They did just come out with some e/w with double flaps just to confuse everyone a little more
