Matchbox Major Pack 4
Ruston-Bucyrus 22RB excavator
Model appeared in 1959 and removed in 1965 according to the Moko Lesney Matchbox Toy Collecting website.
Scale unspecified. According to a correspondent of mine, it could be between 1/92 and 1/100.
All the pictures confirm that Matchbox did not respect the Ruston-Bucyrus “graphics standards”: cabin bordeaux at the bottom, yellow at the top, and chassis dark grey. Normal: for obvious reasons of cost, at Matchbox, a part received only a single colour.
Quotation of essexmodelsandminiatures (itself largely derived from wikipedia).
Ruston-Bucyrus Ltd was an engineering company established in 1930 and jointly owned by Ruston and Hornsby based in Lincoln, England and Bucyrus-Erie based in Bucyrus, Ohio, the latter of which had operational control and into which the excavator manufacturing operation of Ruston and Hornsby was transferred.
The Ruston-Bucyrus 22RB was a middle of the range unit and many are still in use today.
