Nice gun and interesting letter. I see that there were 23 identical guns in the shipment. I find it curious that the bank ordered their guard guns as Police Positive .38's rather than the more powerful Police Positive Specials in .38 Special. Especially as late as 1938 when the memory of gangster era bank robberies must have still been very fresh in everyone's mind. It's always fun to ponder such things isn't it ?
