Hello Peter,
At this time I think that the cap is propably a good one but restored or upgraded, more pictures are necessary. I like some parts but some other a little less.
Which material inside ?
Gaze on the upside lining ?
Part on the front side ?
Close up picture of the visor sewing ?
Close up picture of the buttons sewing ?
Close up picture of the sweatband sewing ?
The name "Lutz" inside, but why U-591, other U-Boot Officers had the same name.
Best regards,
Michel
