dragartist,
what memories that pristine role fit brings back. Keep the pics coming. In general service it soon looked worn but the role equippers did a great job of taking care of it.
On a double MSP drop it was not uncommon for the ramp set of HD rollers to jam after the first platform departed. The second platform would then cut flats in the roller as it departed. Sometimes the HD rollers would be spun up so fast that the grease would melt and you could smell it.
