The materials for the HEL E4A clone are going to come in under $100.
I'm probably going to spend more on gas traveling to the machine tools than I am on the materials.
I've hammered out that the exterior parts will be 4130 chromoly steel because it can be parkerized like the historical can was. It's also easy to work with.
The baffles are going to be 17-4 stainless steel, because... lots of people say to use it.
A down side to this project is, with it mounted to the M16A1 clone, it's not going to fit in my M12 rack. Looks like it will be getting a lot of mounting and dismounting.
