No, sorry - the bulk of this research was from (a lot of) miscellanous parts in
my spares box, and I cannot be sure of the providence of many of my made up
sets, so any info from them would be near worthless.

Unless problems with the use of this mould for the (earlier) ClrYellow prompted
a new mould for the (later) ClrFluorOrange, ClrFluorGreen, Clear.

Strange, that's rather high for the presumed mould-well numbers, usually like 1
06. Perhaps this varient really has got a different official number?

I found it on just one black version - until then I thought the much
more visible gripping extension change had triggered the change from 3941 to
6143.

| (...) I guess it does! I've got some comments below, but for now, let's stick with the two documented part numbers. If someone wants to create these non-functional variations of the part(s), I'm ok with that. But let's not get into xxxxA, xxxxB, (...) (25 years ago, 11-Jan-02, to lugnet.cad.dev.org.ldraw)
