Here is the information for research for the 187th. Unfortunately, you need to go to Maryland and make an appointment to view the documents at the National Archives II at College Park, Maryland.
You can also hire someone to do the research for you at a cost. You can find them on the Internet.
Anyone interested in making an appointment and would like to team up with me, I'm interested in reviewing these documents.
