You are offerding on a brand new CSX Transportation Railroad Earphone Set hard hat attachment style with boom microphone. These are brand new, never used and are really cool for you railroad enthusiasts. Could likely be used in airplanes, helicopters or around other loud equipment.
Manufactured by David Clark Company P/N 40279G-01 Headset / Communication with Boom Mounted Microphone (Hard Hat Attachment Style) For Locomotive, caboose, railway, airplane, helicopter or other uses. The plug in chord can be disconnected and it is a 5 pin connector.I have several sets of these if anyone is interested in multiple items. They have been sitting in an old warehouse for several years so they may have dust on them but they are new and never used.
Thank you for looking at my sale. Good luck!
