Nice work on this Bofors.
As a side note some of those guns ended up in Finland and served very long time along side of Finnish made Bofors.Good guns for the times and very,very small.Finns reworked them few times including tires with a bit ironic HOHOHO pattern-Lapland is one of the homes of Santa Claus.Ian from Forgotten Weapons has really good video of shooting that gun on YT.
