X2 Le Chateau d'Ambreville

First print (1983):  Printed by TSR UK.  The maps in the middle of the booklet are ordered differently, with the Province d'Averoigne as the first, the interior of the chateau as the second page (backside), the dungeon as the third page, and next, the tomb with the illustration above it (backside).  The pronunciation guide at the end was obviously omitted.  Otherwise identical to US version, as far as we know.  Thanks to misterspock for this info and the scan.

Second print (1986):  Printed in France by Publi R.A.  Front and back cover art are swapped for an unknown reason.  Otherwise identical to the First print.  Thanks to Adrian Newman and Géraud Gourjon for this info, and to Adrian Newman for the scan.

E2 Burg Bernstein

Note that the module code is E2 (which stands for "Experten" -- the letter "x" in German is pronounced "ix", which kills the hint to the Expert Set).  Thanks to Uwe Siebel for this info, and to Adrian Newman for the scan.
