There wear several nazi parties and movements in sweden during 1920-1945.
But the larges was NSAP. ca.10.000 members and a lot of suporters during the mid 1930.
In NSAP there was a simular German HJ.org.called Nordisk Ungdom (Nordic Youth)
Here are 3 membership badges.
1.version no.1 (1934-38 )
2.version no.2 (extremly hard to find.existed only for a short time in the NU. movement)
3.version no.3 ( 1939-1950.New name of the Nordisk ungdom, changed to WASA)
Sorry.the pitcures are in wrong order.
.the last black badge is the no.2 version.
