» Topic: PT Mine Study
https://www.ptboatforum.com/cgi-bin/MB2/netboardr.cgi?cid=101&fid=102&tid=5384

In November of 1943 the Bureau of Ordnance completed a study of using PT boats for mine laying. This study was comprehensive, including many mine types that existed in the Navy's inventory. The study also included general arrangement drawings as well as detailed drawings for mine types that could not be accommodated in depth charge racks.

I have attached the general arrangement drawings, as this should hold general interest.
