Simon,
I order two luft crushers from him in NOV 2011 he gave me a 4-6 week time frame. I deployed in FEB 2012 came back in AUG and my caps still were not complete, I emailed him and like 1 week later they showed up finally, if I remember correctly email communication are hit and miss with him.
His hats are truly works of art, but I do not think I will be ordering from him again.
