Are there any documents available online that discuss/provide
the manner in which lube updates were marked ... over time?
For example - I just looked at a car on eBay that has a lube
date added to it that was done by the use of "a patch of black
paint that is then stenciled (decaled) with the date". This was
a car that was built to AAR 1937 standards ... but had been
lubed in Yermo in the middle 60's.
So I'm wondering if I can "just change the year of the lube
date and it is good to go for a steam era car" ??? Or is the
way this particular model is done applicable only to cars
that were lubed off line in the era it is done as?
Or do I also have to change the 'method' that the lube
date was done in order to be prototypically correct for the
era this group is focused on (and myself also!).
And I'm guessing that there might also have been some
changes in terms of the location of the lube data over the
decades. I'm hoping that it is not - but don't want to bid
on it without knowing how much work I need to do ...
Yes, I know that there is a large component of "it depends
upon which RR you are talking about" ... I'm looking more for
some "general practices" (if there were any) and also with
respect to the "believability" of the data and the way it is
applied to the car - because it's a lot easier to just change
the year that to redo the entire lube data.

P.S. An alternative set of answers would be to learn what
methods the UP did - over the years/decades. I am
definitely not "a UP guy".
