Bonjour Gil,
My engine has the number three
I wonder which one the Z01 I already preordered wil have... i guess you will go on being number one

Besides this, I saw the mishap that happened to Henri and I'm glad he was able to put everything back in order and get his number eight working.
Who is number two ?
Besides this, we have the Retrol & Musa HM-01(bought with Enginediy or Stirlingkit) engine, now the B01 Retrol & Okmomodel one, do you know who Retrol is ?
They seem to have a site
https://retrolengine.com/ and build and are not fully sellers
