I will be replacing it with a piece of hardboard with a scrap of MDF board on the rear to strengthen it further.
Also the roadway faded so I will be replacing these and adding an extra building I bought ast a recent toy and train fair.
Just waitng for the glue to set on the MDF and the paint to dry on the hardboard, then I can continue. Watch this space.
Update 2017, the factory has moved and a butcher's shop has been located where the factory used to be.
