WW2 US Navy NCO Rank Insignia Corpsman Stencil
Helmet stencil used during WW2 for the US Navy Corpsman. You can use this stencil to make several ranks from 3'd Class Pharmacist Mate to Chief Pharmacists Mate (medics in other words). The eagle is separate so you can position it appropriately for the rank.
This stencil is suitable for hand or spray painting. Just use masking tape to blank out areas of the stencil you do not require.
