The ERF Lorry (20a) was a simple open back truck, known in the USA as a stake truck. It ranged in colour from deep maroon to dark red, and in its final very short run in 1959 it was fifted with grey plastic wheels instead of metal wheels, making this variant one of the rarest. The first issue was reputedly trimmed in gold (though I have never actually seen one), but all subsequent releases had silver trim. A colour trial model has been found in light green without a brace cast between the cab and the body.
For many years collectors sought another rare version with a spare wheel painted in the body colour lodged behind the cab. This appears to be a genuine variation, although it is difficult to decide whether this was a short-lived intentional version or whether loose wheels somehow got lodged in the gap during the feltling stage and no-one bothered to remove the rogue wheel before painting tool place.
The final variation linked to this model concerns the silvertrim. This was applied by mask spray, but interestingly the replacement model (20b) had the silver trim applied by hand to the earliest release.--Model Collector
