Remote Control Track Section No. 6019 was used with O27 Gauge track and was produced from 1948 up until the end of the Post War Period in 1969.
Early sections were SILVER in color, while those issued after would be chemically blackened. This accounts for the two of the three variations:
Variation A: The track has a chrome or SILVER finish. Produced in 1948.
Variation B: The track has been chemically blackened. Produced 1949-1969.
Variation C: Identical to Variation B except housed in blister packaging and issued under No. B6019 in 1966.
