Cromwell ARV tank in 1-144 update

As I got the question what sources I used to build the tank, it"s quite easy, I checked a lot of Cromwell's in the scale 1/72 and wrote done what they had added. In the next step I generated a 3D drawing to get an idea about the dimensions. So take a look at the picture.
Maybe I will start and print some conversion kits with one of the 3D printer shops.
