Dom, the pictures are much better. Being able to see the contrast between the details allows others to discern and decipher the various attributes that vary among the transitional types.
As a student of cob coinage, I'll offer up my opinion. The obverse (shield) is a Type A. A-P-8(not visible) / O-E-52 According to Dr. Menzel in his publication on transitional cob coinage, Type A is "virtually, always used with the reverse design of Types I to VII. Now, deciphering the details is always the challenge especially with obfuscated details. Of the seven types to consider, there are still minor varieties. The reverse shown is a Type VI known as Triple E's. The minor variety has a central dot in lieu of the "8" for the denomination.
Your description alluding to a Post Transitional reverse is incorrect. It is a Transitional Reverse. The many types can be confusing and having to consider the minor varieties can be overwhelming. There are some cob collectors who only specialize in Transitionals because there are so many.
