Last month I started on respirator #4, then had to set it aside while I filled all the Halloween mask orders coming in.
I have at last had time to get back to it. I redesigned the ventilation holes, and constucted the canister, making it smaller than my previous respirator. Pictured above is the undyed leather mask and canister prototype.
Here is the respirator assembled (except for the straps) and dyed and antiqued. I'm hoping to be able to retail this piece for under $100.
