I recently bought a book off the site. Top notch service from beginning to end. But, that's what one would expect form a high end dealer. I have never bought one stitch of militiaria from Bill though as I'm not into paying extreme retail from anything I own. But, there are plenty out there who love the convenience of point and click shopping where price is no issue. I have seen fakes on his site and he is the only know dealer who publicly refunded a Sham-pain-ruin SS helmet after they were exposed as fake. I'm not sure what your after but, his site does get recent updates and that's nice to see fresh items.. Lots of sites are stale and nothing moves.
Good luck in your ventures.. Head gear especially soft gear Not helmets is really soft right now and its a great time to shop for visor caps and m43's those are now selling for 1/2 what they were and I'm not sure if we will see them any cheaper.
