Welcome to the Board as a poster
No. 150969x looks like a run of the mill 1928AC sold by Auto-Ordnance Corporation/Maguire Industries, Inc. during the 1943 to 1946 time frame. If the property sticker on the butt stock is correct, the original purchaser was the Albany, Georgia Police Department. That information is good to know and provides the new owner a place to turn should they desire more information about this Thompson gun. I would recommend filing a Freedom of Information Act (FOIA) request before contacting the department.
The 1928AC is a common Thompson variation that was sold primarily to law enforcement organizations after the production of the Model of 1928A1Thompson was discontinued (for the M1 Thompson). When Auto-Ordnance Corporation re-organized in 1944 and changed names to Maguire Industries, Inc., the Thompson gun became one of many products of this newly organized corporation under Russell Maguire. The Thompson gun was sold in the Auto-Ordnance Division with long time Auto-Ordnance employee George E. Goll as division president. Original IRS Form 5's will sometimes show Maguire Industries, Inc., Auto-Ordnance Division. Very little documentation exists during this period. It is believed Goll assembled left over parts manufactured by the Auto-Ordnance Bridgeport plant until the supply of usable receivers were exhausted. In essence, what you have is a parts gun from the original manufacturer. No 1928AC Thompson guns with Savage or Colt's receivers are known to exist.
There is no real standardization for the 1928AC variation but No. 150969x fits the pattern of what is normally seen. That said, differences can and do exist between guns. Again, it is a parts gun. Any World War II GI parts would be correct. AOC marked bolts and actuators are not common but I do not believe these parts add any real value to the 1928AC variation. Others may disagree. I looked at No. 150969x when it was first offered for sale. My first impression was it had been refinished, i.e., parkerized. Original finished guns usually show bare metal where the US markings on the receiver were removed. In addition, original finish on barrels and compensators are normally a blueish color. The barrel and compensator appear parkerized grey to me. It is very difficult to judge finish with pictures. An in-person inspection may produce a different opinion.
How a refinished parts gun impacts value is difficult to know. I would expect No. 150969x to be an excellent shooter Thompson gun.
