Ken, et al.,
My research shows three configurations in use at the same time in the first
decade of the 20th century. No end ladders or platforms (XA-1 cars were
delivered from Pullman Standard in this configuration), brake platform but
no end ladders (XA-2 cars were delivered in this configuration), and both
end ladders and platform (standard practice by 1912, but little to no
information on when older cars were retrofitted). Since there is no
definitive information on the 1889-90 horse cars that were rebuilt as XB-1
barrel cars, I would guess that they were originally built without end
ladders or platforms. I doubt that the 1907 rebuild would have been very
extensive, but it's impossible to know for sure whether or not a platform or
end ladder was added then. Any of the three options could be correct for
this car, and lacking photographs, you can take your pick. Since the car ran
until 1923, it's highly probably that grab ladder and platform were added at
some point. That means I can model it for whatever period I want between
1907-1923.

Nelson,
Pictures, pictures, must have pictures.
I would add the ladder and platforn, while the diagram does not show
it diagrams for other cars don't show ladders either. Also a car
being rebuilt would be brought to current standards. It probably
would not be a ladder as such but grab irons fastened to beams, look
at stock cars.
I am not an expert on air brakes but have picked up a couple of
Westinghouse booklets.
In 1907 you wouldn't have KC type, I don't believe that came into
being untill the '30's.
I have a book from 1911 that just calles it the "quick action triple
valve"with out mentioning a letter. A 1941 pamphlet says the K has
replaced the H model. That said I don't see a visual difference
between the KC and the "quick action" so I would use the KC castings
and arrangement.
