Cooper Type 8a

I am fairly unsure on this classification but yet trying to keep this as type 8a. Here's the reason - as per Cooper, type 8a is rough rectangle with 3 diminishing line. Which, this cover matches with but the next criteria of 'figures are small and neat' is what is creating doubt. As this cover figure definitely not small. So till the time, I get more clarity, I am assuming it as type 8a only.

Cancel bears office number of 364 (Nangud)
