I have won this Polish Wielkopolska Army Lieutenant's 1919 Cap, is it 100% original Prewar, please ?
As it has old Polish newspaper inside the sweatband, hopefully this would mean that it was done at the time and the lining looks like the kind of material you would use when materials were in short supply just after WW1.
Here are its photographs.
Thank you very much for your help, in advance
I look forward to reading your knowledgeable opinions, as soon as possible.
