My grandpa with a "Autocarro Leggero SPA 38R" used in Libia campaign

SPA 38R field machine shop

..a repair on his SPA 38R field machine shop

just a Gilera 500 LTE

...a his friend on another Gilera ...

..I love this rough LTE 500.. it's like my ideal bobber, powder included..

..on a 1920' "normale" type MotoGuzzi ...

An English gun at El Alamein ...

... I am not sure but I think this bike it's a MAS 500 SS , what do you think?

I have some doubts that it can be a English motorcycle...
