RARE aviation helmet of leather (?deer?) with wool lining. In very good condition considering its age. Some wear to the leather edges, leather chin strap torn in the middle. But the leather & wool is still supple & soft. The pat. label is detached but still w/helmet. You can look up the patent to see details of design: https://patentimages.storage.googleapis.com/8a/4c/09/8cda51a7bb68be/US1655007.pdf
All those I've seen for sale in good condition are going for a lot more along w/shipping & tax. So this price is FIRM! Local porch pickup in Providence; cash only. BUT I could mail to you w/shipping. Then payment can be paypal or zelle.
