Hydro date says 3/13, as in this month. As in you have a full 5 years.
Born date 2006.
It comes with the original reg. The lip of the bonnet is slightly bent, as show in pics, but it does not affect its ability to seal.
Bonnet is also showing slight discoloration, the white in the threads. I sharpied over some of it in the other picture.
No dings or scratches on the tank itself.
Everything works fine
Also have a 68/45 Nitroduck close to hydro.
