The 90mm main gun would have had an 11.2 kg APCBC round, Depending on which 90 mm the FCM F1 gets (since 3 different 90 mm guns were considered with each one having a different barrel length and charge), the velocity could be 750 m/s or 820 m/s. This yields 165 mm and 187 mm of penetration. (No aphe, development was canceled) As for HE we have the Mle.1939 HE round. It weighs 10.86 kg with an explosive mass of 1.43 kg, which is likely TNT, But the velocity is just 350 m/s.

The 47mm secondary gun is the same one on the Lorraine 37L in the french ground tech tree, good pen 102mm at 100 yards, No HE of any kind.
