Dimensions are 112x86x68 cms (LxHxW). It was originally installed on 17th July 2014, so it's pretty old. It is still working and holding a freezer temperature, but has started rattling a bit so I am not willing to trust it for long term storage of large quantities of produce. However, you may be able to fix it or trust the rattle, which may be just a loose pipe, or want to use it to freeze stuff down rather than long term storage.
I have to load it into my car to take it to the recycling depot anyway, so I will bring it to you within a few miles radius of St Albans. You might prefer to come and help me load and unload it if you want to avoid it being damaged in transit, as I am single-handed. It is defrosting at the moment and will be dry.
