Vintage formica extending table (Beckenham BR3)

Vintage table, has had a lot of use over many years. Two faint round marks on the top (see picture). The stripe on the second picture showing it extended is only a reflection from the window. Dimensions when extended 50" x 27" x 31" high. When closed 27" x 27" x 31" high. It would be good if this could be collected quickly as the builders would like it out of their way.
