Chinook boom, three sizes available. Suitable for those who want to complete their brand collection. The blue rubber part of the mast grip has aged cracks (photos 7 and 12), but no other damage is visible. It has been used for many years. Please refrain from purchasing if you are looking for a pristine item. Negative aspects have been shown in the photos. This item was received from someone else, and I am considering using it myself. I will sell it if there is a purchase. *Harness lines are not included. They will be removed. The uphaul line and the sheet will be included as shown in the photos. Hand-delivery is OK. For delivery, it will be sent cash on delivery, probably via Yamato Transport. I will consult with you. Please let me know the delivery address, and I will arrange it.
