Extending wooden table. Vintage (Woodingdean BN2)

Heals's, I think, iconic 20thC table. Green painted wooden frame. Large square wooden top that folds in half and slides across. Fitted together with series of alun keys. Is assembled as regards the frame, which would fit in a large car probably, or van. The top is folded and separate, ready to take. And take with you the two little bits of wood that need to be screwed back in place when it reaches its new home.
