Does anyone recognise these doors? My house is a reconstructed farm building and the doors were apparently sourced from an institute of some sort on The Wirral. Anyone involved in the building work, from the late '80's, has passed on.
The locks are unique in that they could be locked twice, with two different keys (I don't have any keys). I would imagine that rooms needed to be locked and, at times double locked, by a person in authority. Possibly to keep someone inside secure or access strictly controlled.
They are larger than average in size and beautifully made. They all came with original architraves so were deemed valuable enough to be carefully salvaged at the time.
I've searched many times and not found anything definitive. Any information would be appreciated.
