Type Z (?) Harness Info/Item required

Afternoon everyone,

One thing we (The Bluebird Project) haven’t sourced for the rebuilt boat yet is a replacement harness for the cockpit. (This would be for visual use only- we’ll use something modern for actually running the boat.)

I’ve been led to believe that the harness was a blue ‘GQ Type Z’, though it carried an ‘Irvin’ logo on it which I was told is unusual?. Pics are scant but here’s some- first colour pic is just off Google and is I believe what we are after. The next couple show the actual harness in the boat, and the final one shows it after recovery in 1967- note the ‘Irvin’ logo and single bolt fixing that has been torn out, down by the diver’s foot.

Any help with identifying or supplying one of these would be very much appreciated…
