IMO, no AS 37 in east african campaign ... AS 37 was designed for saharian use, and issued to Lybia ...
May be some TL37 ( generally towing 75 and 100 mm guns)
for sure OM32 , OM35, OM36 , Fiat 15 ( 21 in use ) , SPA 25 c10, Fiat Dovunque 33 ( 82 in use ) , Lancia RO ( in use in "Autogruppo Pesante di Manovra" ...
i'm
sure that the elefantino was not towed, except by a mule , been to light ( 277 kg ) ... and mostly broken in 8 packs .
To tow this piece, the tractor OCI-780 CM and the light tank L3 were used, but these projects were soon abandoned as the gun was subjected to braking at the axles spindles and shanks.
PS : si t'avais posé la question en français ma réponse aurait été plus fastoche
