Buy another old helmet of the same make, model, size, probably off Ebay. Join the two together side by side with a hook, attach a couple of bungees to the lower sides and then offer them to the girl in your office known to all & sundry as Norma. Norma Snockers, works in admin probably. She'll be chuffed to bits at your thoughfulness and you can expect a reward from her commensurate with your act of kindness & caring. Good luck with it all.
