"old" should be removed from part name.
(Each part at some point in time will become "old".)

Maybe it got released with the recent Parts update as 458c01.dat.
This is a frequent annoyance which recently got solved
by introducing the new u...dat naming scheme.

Maybe all currentl x...dat files on the PT should be moved to
a new u....dat number to avoid this trouble in future?

Yes, it got released with 2010-1.
I don't think that we should change all the current x... name to u... names. Just let us get that parts out and this failure will not be present anymore.

The tyre should be colour 256 Rubber_Black, and colour 382 does not appear in the 2010-03-05 update of ldconfig.ldr as far as I can see.

Changed color black to rubber_black.
Color 382 is an old color number. That is true. It is not in LDConfig.ldr. Thats also true. But as this file has been submitted long before the current LDConfig.ldr has been established this number is still valid. If you have a good alternative from LDConfig.ldr range, please let me know.

Reviewer: Steffen

I'd like to drop a few notes here:

Mike is right above. The ldconfig.ldr is much newer than many
parts and therefore on its own may have bugs, e.g. missing colors.
It needs to be carefully considered each time when encountering
the problem of a color not listed in it if it's the part that is
flawy or the ldconfig.ldr.

Having said that, I'd like to request here that a new color
0 !COLOUR Electric_Contact_Steel_Matt
should be introduced in ldconfig.ldr, in addition to the existing
0 !COLOUR Electric_Contact_Alloy
0 !COLOUR Electric_Contact_Copper
and especially in addition to the existing
0 !COLOUR Chrome_Silver

Why that? Here are my reasons:

a) Chrome_Silver produces a high-polished, chromium look
(like for the 12V Train Electric Rails, which is good there).
However, the wheel axles are usually not that shiny and need
a more dull, matt look.

b) High end renderers usually supply a range of metal color
configurations, amongst them:
- highly-polished chrome
- copper
- alloy
and
- steel, matt
I'd like to be able to use those colors, instead of falling back
to alloy here.

c) The axle definetely is not made of alloy as it then would
be trivially bendable. Instead, it's AFAIK made of steel.
So it should get a steel material assigned.

d) The new color can be used on all existing steel wheel axles then
which would make them look uniform. Good Thing (TM).
However, don't forget: there some older wheels which have a
brass instead of steel axle!

The whole discussion of course collapses if I have overlooked something
and somebody can point out a color in ldconfig.ldr that already
has the above properties.

As all other wheels with axle do have color 8 Dark_Gray as color and this one is more like brass, I think we have here exact that case. The best current in LDconfig.ldr color is IMHO 495 Electric_Contact_Copper if I look at the intend of the author. But this is not correct either. For this we would need another NEW color in LDConfig.ldr or we just leave it as it is.

My fault: I fell for a translation issue here.
I somehow thought that "alloy" meant "aluminium". Sorry for that.
Instead of trusting my internal translation memory, I should
have looked that up from the start.

Nevertheless: using copper color here is plain wrong.
The axle isn't made of copper. I remember it being brass
or brass-alike.

I strongly prefer the addition of missing colors to ldconfig.ldr
instead of applying workarounds
by using existing colors which have a false logic
(here: "copper")

Reviewer: anathema

Thinking further...

- I don't believe we should be speculating on the type(s) of metals used by TLG

- we should IMO have ldconfig colours for these metals

- the colours should be named for the appearance (eg 'white metal') rather than the material, unless the material is unambiguous or the name of the metal is also the name of the colour (eg 'copper')

- while this particular part pre-dates the current ldconfig, it's also an unofficial part and a change in the specs should result in it being held until it conforms (for example, stickers on the PT which use colour-47 are routinely held until changed to use colour-16 even when the part pre-dates the change to the sticker specs)

- steel is also an alloy ;-)

By the way: to name this file consistent with the other wheels,
"with rubber" should be replaced by "with Tyre".
Holding for that reason.

I would have to dig out the actual parts to check, but ISTR seeing this part with both a yellow-metal and a white-metal axle. I'm pretty sure the white-metal one was more common.

Thanks for all that helping comments!
I mainly agree with all your points, except for these two:

- "alloy" is too generic a name IMHO to use as a color name.
Better: "steel", "copper", "brass", "chrome" etc.
Even if we don't know the exact metal LEGO used, in the color table
this makes the colors clearly suggest how they should look like.
Should later be discovered that the metal is a different one,
the file could be corrected similar to other files having
geometric flaws etc.

- "white metal" might chemically describe the class of alloy
being used here http://en.wikipedia.org/wiki/White_metal
, however, I find it too generic for the color table.
Imagine we would have named color "brown" there
"earth color". This would be too generic, and could vary from
"sand" to "black" :-(

Difficult issue!

Don't believe everything on Wikipedia ;-)

'White metal' is also used as a generic term for any grey/silver-coloured metal, regardless of its composition.

Similarly, 'yellow metal' covers everything from brass to gold.

I agree that 'alloy' should not be used as a description of colour, but I would also argue against using metal names unless it's completely unambiguous. For example, 'aluminium' might seem clear, but since aluminium can be anodized to a variety of finishes it isn't really appropriate as a description of colour IMO :-)

'Copper' and probably 'brass' (another alloy!) are clear enough, but I'd be very wary about using, say, 'steel' as a description of colour.

it's a bit scary to see these happen "behind our backs" without

Naming: "...with Spokes Conical" means that the spokes are conical, not the wheel :-)

I suggest "Train Wheel Conical with Spokes (...)", which also addresses Steffen's point about the word 'Old'.

I asked that question already in 2009 on the wheels:
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/568c01.dat
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/244c01.dat
As I do not have all parts from that period I am unsure, but I believe they are modelling the same real part.
