Hi Steve and WW2 Hunter, make that three as I live just up the road, not far from Losheimergraben..... I am British and have been involved in MV collecting for a number of years. Recently I helped a friend acquire the roof from a Jpz IV that was destroyed near Dom Butgenbach.
A good book is 'The Key to the Bulge" by Stephen M. Rusiecki. It is published by Stackpole books. Although it mainly covers the fighting for Losheimergraben, it has an extensive account of the I&R platoon action at Lanzerath.
