They are corect photos that is 37mm Bofors with Polish infantery soliders but you can use secound photo for polish bofors in Tobruk unit 470
BTW I found in French unit 481 and Vichy OOB too unit 481 mysterious 37mm SA37 ATG which I can't found any info in internet. Photo is Pm9427.lbm which is Polish cavalry soliders with french helmets with bofors. I'm just courious that french also have some 37mm bofors from poland like UK which buy them in summer 1939 or from sweden.
Or meby that is mistake and this is this gun:
37 mm de Marine Anti-Char
This was a modified naval weapon used as an anti-tank gun by French Forces in Tunisia 1942-43. Thirty Six converted.
that is where I found this
