Unknown size. Standard winter pattern helmet from the 101 series. Brown goatskin leather with the usual lambswool lining. The leather is generally in very good supple condition but there is some rubbing and wear on the earpieces. Most of the straps are good but the buckles are corroded, as are the oxygen mask clips. Unfortunately the crown strap has issues - the front clip is in place but the webbing that attaches to it is broken. The strap can be fed through the helmet channel as intended and could be replaced. The lining is good but a bit grubby. All the avionics have been removed so there is no loom, receivers or throatmicrophones. Label absent. Stock code H17584.
