I thought the discussion was about a piton. Where have hangers with personalized markings been removed?
Also, could it be possible that the fixed pin had become loose from recent rain, high route traffic, etc? Maybe someone climbing the route removed it without any tools because it was loose. Kind of like the missing hanger on Erectile Dysfunction?
It was. I just had to bring up the discussion of replacing worn pins again and clink's mind wanders.
There are only a couple cases I can think of where people got emotional about removing old hardware.
The bad thing about RK's hangers is even though they are really cool and historic, they are the lever out type usually with smallish holes and compared with the modern hangers they are thin and potentially weak.
I wouldn't replace a bolt with out replacing the hanger and I don't know anyone else that has done that either.
The Merry Cranksters left the old bolts in cobbles on Fifty Meter Must and I assume placed the new bolts close to them in matrix. Trying to remove bolts from cobbles (if they are fairly small) could definitely alter the route.
I still haven't climbed that route to see exactly what they did.
I totally understand the historic context and the sentimentality and I always try to keep that in mind if I am working to restore an old route. No one wants to see the history disappear but to me the real legacy is the route itself because it will last longer than the hardware (well...maybe...it is after all Mud and Crud).
I agree with your assessment of the piton disappearance Nelkins. Very likely that is what happened.
