I have been working on this stainless steel harness for a bit as a prototype. It is made from a rough from the hammer blank and is 304 16g stainless steel, it would fit someone 5'10"-6'1" up to 230 pounds. My chest is 48 and my waist is 38 and it fits me perfectly. It could probably fit someone up to 40" and down to 36" waist size. the top is roped and the edges are bumped out and stepped down on the side gussets and tassets around where the codpiece would go.
right now I still have to put the buckles on the sides attach the back plate to the straps and polish it up. If someone is interested in finishing it up I will let it go for 400 bucks if I have to take it apart polish and strap it it would be 500 bucks

I will get some better photos later when my camera charges. Also, please disregard my messy office my 3 year old rolled through there this morning
Thanks for looking!
