Apologize for the blurry one, hands shake too much:
On the left is a top mounted stemmed AAI, on the right is a top mounted stemmed AA. The two are basically identical in every respect, thinking the AA led to the AAI which became a slightly modified version. Similiar to the AI, AII, AIII, AIV models in the early period. This one is marked "A"A, the name on the movement is "O. BurkI", I also have a later one around here somewhere with the stem at 3 O' Clock but couldn't find it today. Have this one partially torn down to do some repairs but the parts are identical and interchangable with the AAI for the most part.
