"Hackenberg, Block 5 Artillery casemate for 3 x 75-mm guns"

Ah, sweet memories. I did a tour of french fortresses seven years ago. On the Maginot line I visited Hackenberg and Fermont from the inside plus some others works from the outside. Bought all the materials they had, pestered the staff for info etc. If you have any question ask.

"Each bunker which projected above ground was essentially "custom designed" to fit the terrain available; making recreating the magniot line problematic without making a lot of generic icons..."

While the bunkers were modified to fit local conditions they were based on standardized patterns drawn by the CORF (Commission d'Organisation des R�gions Fortifi�es). While a generic icon would not be 100% it will be good enough.
Let's take the Bloc 5 for example. This is a textbook "casemate the flanquement". Each fort was supposed to have two of them (in some cases they were replaced by turrets fulfilling the same mission). They were the most important blocs of the fortress as they were supposed to cover the intervals between one fortress and the other, so that the germans couldn't just break throught there. You can find the same type of bloc at Fermont, for example, where it is labelled Bloc 4.
The only substantial difference is the position of the lift.
