Perhaps one or more of you "monochromatic colour" interpreting geniuses could possibly lend some thought to the paint on this Mine Motor.
Are we looking at a Black and Yellow ended Motor or is the side colour actually Red?
The C&S would have delivered these Motors by the Boxcar loads since after 1927 or thereabouts, these neat little locomotives profusely populated most mines.
Well SP, no different to the examination of the variance of Insulator glass colour I suppose.
I was wondering since early Locomotives were black at the period of the introduction of Electrical power, this photo is supposedly from the mid-30's, at a time where Caterpillar changed from spiffy Grey to Highway Yellow.
About that time the practice started to reach other areas of the construction and mining industries, hence my query. And as I mentioned there would be relevance to this for any modellers wishing to show these in a setting adjacent to their railroad models, either at a Mine or Loading Dock.
Since there has been a lot of discussion lately concerning interpreting colour from a B&W photograph I see no difference here and recent perusal of period Catalogs seem to have presented a different tone to that of ordinary Black. After all these machines were new and innovative in Cost reduction, the addition of Red paint colour would enhance and influence sales I think.
I think you are on to something, and your answer will
likely be found in period catalogues. Much research
around those insulators has dramatically advanced our
understanding of them in the past 15 years, using the
old industry periodical publications and catalogues. The
internet has proven to be a real friend to research like
What would be totally different about glass colors vs.
paint colors, is that a lot of care was given to paint color,
and keeping it consistent was important. With insulators,
glass batches varied with every scoop shovel of sand and
soda tossed into the furnace. And they most certainly did
not care about color .... at least not before 1930.
