Nuno has very kindly put the original reports on the Italian tanks online. You do unfortunately need a SCRIBD account to be able to read them.

These are the reports that were produced by the UK School of Tank Technology in Chertsey, who undertook detailed examination of captured Axis and gifted Allied tanks, e.g. the Soviet KV-1 and T34 models. They are illuminating because they tell us what experts thought in the day, rather than through the distorted lens of 70 years onwards.

M11/39 at this link (for completeness – this tank did not serve in CRUSADER)

M13/40 at this link (the medium tank that equipped Ariete armoured division in CRUSADER)

Happy reading.
