GPO Stores managers stash.
Its not often I get my hands on a collection of such nice original GPO telephones. He was in charge of a stores and when the GPO was clearing out their telephones that were coming in from upgrades he had the pick of the very best. He inspected them and only kept the very best examples and they have been stored in these plastic bags ever since. The ABS versions will be sold un-restored but tested as working and checked for any damage before being sent out as is. It will be up to you to clean polish and ad a modern line in plug and electronic microphone and if you require the parts I can supply them at extra cost. They will be priced at £55 for red and all other colours £50.
