Thank you, Charlie, for your help.
FYI, there are 27 low-res (360x480 dpi) photos of the last REVENUE frieghts over Cumbres, August 28 & 29, 1968, on the preview slideshow - part 2, on the "Save #483" website at [
www.drgw483.net] . All of these photos - and 56 more from December, 1961 through December, 1968 - are available in hi-res (1200x1600 dpi) on the "Help Save #483 Screen Saver". See the above website for details.
(Even though the preview has been split into two slideshows, they are still quite large and do not work well via dial-up connections - I recommend them for DSL only.)
