Included with this accessory was an unmarked bag of lichen (No. 448-5) that was used to "camouflage" the launcher. This is a difficult accessory to locate, especially with the No. 448-7 ORANGE picture box.
Lionel showed this accessory in both the catalogs and the instruction sheet, No. 448-6 dated 8-61, as having a man at the control panel, but it was not produced this way. It is also shown in the Lionel Service Manual as having controls and gauges on the control panel similar to the 6544 but this also was not produced this way. This was probably done to reduce production cost. There are no variations.
