After the war it was wrongly assumed for a time that H38 was the official name of the tank with the new engine but without the new gun and that H39 was the name of the type that had both major improvements.
Efter krigen blev det en overgang fejlagtigt troet, at "H 38" var det officielle navn til kampvognen med den nye motor men uden den nye kanon og "H 39" navnen til den type der havde begge forbedringer.
