This is a special limited edition to celebrate the 50th anniversary of the introduction of the SW1. It has a newly designed bodywork and different wheels (same as on the SA1 but with different tires). This example is serial number 6 of 100.
Mechanically identical to the normal SW1 apart from the slightly different wheel diameters. The bodywork is much enhanced with a closed style cab and covered load bay. Other minor cosmetic enhancements include a pair of headlights, a chimney cowl and special wording for this edition. This example is unfired and I intend leaving it that way.| Make | Mamod |
