This large Site Dumper is the larger version of the Matchbox No.2A Dumper and was developed by Lesney to be part of the "Large Lesney Toys" series. It was made by the model & tool maker Ron Dix who left Lesney in 1952 to create his own company ( Condon ) and ha was given this production ready tool to start his company. Ron Dix was replaced by Jack Oddel within Lesney, the rest is history. So this model was fully developed by Lesney and never put into production, it was made for a short time by Condon before this company went under. Red, yellow wheels, played with, driver is missing.
