Very old tin from the era before printed tin became the norm, it's covered with printed paper which is in fair condition for the age.
Tin material is slightly discoloured but NOT rusty.
Labeling shows original name of this company before the brand purchased by United Biscuits.
The weight has been overprinted, presumably as that was cheaper than a new print run when the weight was reduced by 4 ozs - that's still done today!
Collection from near Kettering football ground will allow buyer to inspect before cash purchase but will pack and post if collection not convenient - this at cost and to be advised after sale and packing.
