main PCB is marked: "LC" on component side ("LC" is the Italian for "Lato Componenti" which translates to "Components Side")
main PCB is marked: "LS" on solder side ("LS" is the Italian for "Lato Saldature" which translates to "Solders Side")
This PCB has been manufactured in Italy, roms are the same as "Cobra-Command (Japan)" already in MAME, but split into half-size EPROM chips

update 20200321: found a second PCB for the same game. Confirmed dump, added pics and chips clocks.

update 20200322: dumped PROMs and PAL.

update 20200323: thanks to Osso, the last PROM has been found and dumped.
