Original Tilley lamp brass harp hanger.
It was for KL80 model lamps, as demonstrated in last photo.
PLEASE NOTE, LAMP IN LAST PHOTO IS NOT FOR SALE IN THIS LISTING. THIS LISTING IS FOR THE BRASS HANGER ONLY.
It is tarnished and would need a good clean up, but structurally sound.
Postage is £9.95 as Royal Mail charge for size as well as weight now and will be well packed.
Good luck.
