Interesting.....When I lay the gauges side by side and align the ":" marks, the 05B motor stick is slightly longer as seen visually at the handle end.
What part of the seal is the measurement made to......the closest to the bell or the seal edge closer to the stick end.
I can take measurements. As for the color, it still looks pink (salmon) even on the part that sits into the handle. I would think that hidden area would not fade.
