Miscellaneous, Wax Seal

On reverse of the shown Nairn Publication Envelope, dated July 1941,  i found a Wax Seal, apparently used by the Nairn Company. The Text on the Seal Reads NAIRN E.T.C LTD (Nairn Eastern Transport Company L.T.D.). The only one so far i am aware of it and I a happy to be able to show it here. Note: Item not (yet) in my collection.
