If it's the Slartibartfast guy he's been thru here years ago with that name followed by other puppet accounts. He's your standard run of the mill recaster. Doesnt care who he steals from and doesn't care about quality either.
That said, there are better lids than the GMH available IMO, such as the FP premium and the FPH2, unless you need a smaller helmet and are looking for the preproduction 2 type of damage.
