Service cap of the 1920s

An extremely rare and interesting cap in a good collector's condition. Unfortunately, we could not accurately attribute the item, but we can say with confidence about its authenticity and the time of release – the end of the 1920s. The band is black velvet, the crown of the sea-green cloth, the edges are crimson, the visor is plastic. The manufacturer's stamp is applied in silver on the lining. The top of the crown has multiple moth damage. The star of the sample of 1922 was put by us, but it is quite likely that in its place there should be another cockade.
