Recently there are some Oils Matchbox tribute trucks occasionally popping up on ebay, e.g.: http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=200367029201&ssPageName=ADME:X:RTQ:AU:1123

These do not seem to be official Matchbox releases. Does anyone have any idea about the origin of these trucks? Are they simply fan-made or is there some kind of Matchbox custom shop selling them? Are they in any way officially licensed merchandise?

Cheers,

Stephan
