I found an iteration on the jacket you named pic related. It does not look to be the same as the pictured jackets you posted. Other than that I've found a couple recreations of natsoc jackets, the first listed being sold as a "KRIEGSMARINE WW2 German Jacket – U-Boat Captain Leather Pea Coat". I hope this helps.
