Husqvarna based Laverda (LH = Laverda-Husqvarna) but heavily modified by Laverda. So i'm not shure if it is still of Swedish origin. La peinture, la peinture! Et un peu d'habillage. C'est à peu près tout...
Husqvarna furnished the engines, Laverda modified them (other carburators), build the motorbikes around the Husqvarna engine, indeed similar to Huaqvarna.

A bit of a squeeze 2 up, too small for a 750, I reckon 500 or 550, not factory paint so hard to tell.
