This was posted in a thread in CMFB page but I thought it should also be posted in the general forum. Here is a link to a very large and free collection of period maps of Europe from 1943-1944. For the Italy section there is also the City Map plans available. The central Europe section should cover the area for the next module for CMRT. I think a few people here will find this to be very interesting. Big shout out to @AlsatianFelix for the original find.

Here too is the map collection from the University of Texas. They also have some amazing maps.

As a side note McMaster is not too far from home and in a few years when my oldest is ready for university, I think I will have to encourage her to take a campus tour and I shall get lost in the map room.....
